ZicNet setup support

When you need help, send your device, client app, error screenshot and time of issue so support can check faster.

Details to send first

ZicNet support works best with details that can be checked: device, Happ app state, tested location, screenshot, ISP, and issue time. This helps separate app issues, subscription-link issues, ISP routing issues, and billing questions.

  • Device and operating system.
  • Where Happ was installed from and its version if known.
  • Tested location and current ISP or Wi-Fi.
  • Screenshot or the exact step that fails.

Quick message template

Send support this format so the issue can be checked faster:

  • Device + operating system
  • Happ app and version if known
  • Plan active or just renewed
  • Locations already tested
  • Current ISP or Wi-Fi
  • Screenshot + issue time

Which channel to use

Telegram

Best for screenshots, short videos, and quick setup exchanges while installing Happ.

Zalo

A familiar channel for Vietnamese users who need setup help, subscription-link checks, or quick pre-purchase questions.

Email

Use email for billing, refunds, account requests, or anything that needs a clear handling history.

Quick answers before contacting support

Common issues should be checked in order so you do not reinstall the app or switch servers unnecessarily.

Subscription link will not import

Copy the full link from the ZicNet panel, remove extra spaces, import it into Happ again, and refresh the subscription. Do not post your full subscription link in public groups.

Cannot open or sign in to the panel

If vpn.zicnet.vn will not open or panel sign-in fails, check the base network with Happ turned off, try another browser or private tab, confirm the correct email/account, and capture the error with private data hidden. Do not post passwords, sign-in codes, subscription links, or payment details publicly.

Wrong panel email or account

If you bought or renewed a plan but the panel still looks empty, confirm you are signed in with the same email/account used for payment. Sign out and sign in again with the correct account, and do not create another account or buy again before support checks it. When contacting support, hide email/account ID and include payment time or transaction reference if available.

No sign-in code or forgotten panel password

If the panel shows a sign-in code or account recovery step, use only vpn.zicnet.vn, confirm the correct email, check spam or promotions, and wait a few minutes before requesting again. Do not enter passwords or sign-in codes on unknown links. If it still fails, send a screenshot with email/account ID hidden, attempt time, browser, and ISP/Wi-Fi.

Happ says the subscription link is invalid

If Happ shows invalid URL, invalid subscription, or an invalid-link message, copy the latest link from the panel again, confirm you are signed in to the correct account, avoid missing characters or extra spaces, and import again. If it still fails, send a screenshot with the subscription link hidden, device, Happ version if visible, and issue time.

QR or clipboard copy misses characters

If copying through QR, clipboard, or a share button makes Happ fail, open the ZicNet panel in a browser, copy the latest subscription link again, paste it into notes to check for line breaks, a missing final character, or extra spaces, then import it into Happ again. Do not post the full link publicly; if it still fails, send a screenshot with the link hidden.

Should I send or share my subscription link?

Do not post the full subscription link in a public group or share it for someone else to use. The link loads your ZicNet account configuration and servers into Happ. If you need support, hide the link, hide account email/ID, and send only the error screenshot, device, ISP/Wi-Fi, tested location, and issue time.

Where should I download Happ safely?

Use the ZicNet Download page to choose the right device: Google Play for Android, App Store for iOS, and the official release for Windows or macOS. Avoid unknown file links. After installing, sign in to the ZicNet panel, copy the subscription link, then import or refresh it in Happ.

Device date, time, or time zone is wrong

If the device date, time, time zone, or clock is off, Happ/VMess may show unusual connection errors. Enable automatic date and time, confirm the time zone, reopen Happ, refresh the subscription, then try Singapore or Japan. If it still fails, send a screenshot with the subscription link hidden, device, ISP/Wi-Fi, and issue time.

Happ asks for VPN or network permission

This is a normal step so Happ can create the VPN connection on Android or iPhone. Allow the VPN/network permission; if you already denied it, reopen the system permission setting, then refresh or import the subscription link again. If it still gets stuck, send a screenshot with private data hidden.

Happ is connected but a specific app or website still fails

If Happ shows connected but only one app or website fails, test 2-3 normal websites, try Singapore or Japan, switch between Wi-Fi and mobile data, and reopen the app or website. That app/site may block VPN traffic or have its own issue; send the app/domain, location, ISP, issue time, and a screenshot with private data hidden.

Happ shows a DNS error or cannot resolve domains

If Happ shows a DNS error, cannot resolve a domain, or opens IP addresses but not websites, disconnect Happ and test the base network first, turn off Private DNS or adblock DNS if you enabled it, check system proxy settings, refresh the subscription, then try Singapore or Japan. Do not change DNS blindly on a work or school device. If it still fails, send the failing domain, device, OS, ISP/Wi-Fi, location, issue time, and a screenshot with private data hidden.

Hotel or cafe Wi-Fi asks for sign-in before Happ can connect

If hotel, cafe, airport, school, or other public Wi-Fi opens a sign-in page or captive portal before internet works, disconnect Happ first, open a normal browser to complete the trusted Wi-Fi login or terms page, confirm websites open with VPN off, then reopen Happ, refresh the subscription, and try Singapore or Japan. Do not enter ZicNet passwords, panel codes, payment details, or subscription links into unknown Wi-Fi pages. If it still fails, compare with mobile data and send the Wi-Fi venue/name, device, OS, ISP/Wi-Fi, location, issue time, and a private-data-hidden screenshot.

Happ or the VPN icon is connected but the device has no internet

If Happ or the system VPN icon shows connected but every app or website has no internet, disconnect Happ and open a website with VPN off to separate the base network from the VPN route. Then refresh the subscription, try Singapore or Japan, compare Wi-Fi with mobile data, and restart the device. If internet fails only while Happ is on, send device, OS, ISP/Wi-Fi, tested location, issue time, and a screenshot with private data hidden.

Happ is blocked by firewall, antivirus, or system proxy

If the device reports that a firewall, antivirus, security app, or system proxy is blocking Happ, do not disable security permanently. Install or update Happ from the official source, allow Happ in the firewall only if it is the app you just installed, check whether the proxy belongs to work or school, refresh the subscription, then try Singapore or Japan. If it still fails, send a screenshot with private data hidden, device, OS, security/proxy app if any, ISP/Wi-Fi, location, and issue time.

Happ connects but feels slow or laggy

Speed depends on the device, ISP, Wi-Fi, time of use, and location. Test the same real task, try Singapore or Japan first, compare Wi-Fi with mobile data, then record the location, test time, and slow app/website. Do not switch apps immediately before comparing under the same conditions.

Happ disconnects when the screen is off or in the background

If Happ disconnects after the screen turns off, after switching apps, or after the device rests, check Battery Saver/Data Saver and background activity or data permissions for Happ. On iPhone, check Low Power Mode and Background App Refresh. Then reopen Happ, refresh the subscription, and test Singapore or Japan. If it still disconnects, send device, OS, ISP/Wi-Fi, location, and issue time.

Happ shows timeout or route error when connecting

If Happ shows timeout, handshake failure, or route error when you tap connect, refresh the subscription, confirm the plan is active, try Singapore or Japan, then compare Wi-Fi with mobile data to separate a route issue from an ISP issue. Do not switch apps or edit the config manually before recording the exact error text, location, ISP/Wi-Fi, device, and issue time.

Happ shows TLS, SSL, or certificate errors

If Happ shows a TLS, SSL, certificate, or x509 error, do not ignore certificate warnings or edit the config manually. Check the device date, time, and time zone, refresh the subscription, copy the latest link from the panel, try Singapore or Japan, then compare Wi-Fi with mobile data. If it persists, send a screenshot with the subscription link hidden, device, OS, Happ version, ISP/Wi-Fi, location, and issue time.

Servers appear but no location responds

If Happ shows the server list but every location fails to respond, confirm the plan is active, refresh the subscription, check public server status, then retry on both Wi-Fi and mobile data. If all locations still fail, send a screenshot with the subscription link hidden, tested locations, ISP/Wi-Fi, device, and issue time so support can separate plan, route, app, or network issues.

Plan expired

Check the plan status in the panel, renew if needed, then copy the latest subscription link and refresh it in Happ.

Renewed but Happ has not updated

If the panel is active but Happ still shows an error or no new servers, copy the latest subscription link, import or refresh it in Happ, then try Singapore or Japan first.

Registered in the panel but not sure which plan to buy

Do not buy multiple times if you are unsure. Open pricing, choose by the real number of devices, expected data or usage time, and locations you need to test. If it is still unclear, contact support before paying; after purchase, copy the subscription link in the panel and import or refresh it in Happ.

View the detailed guide

Where do I get the subscription link after buying?

After purchase, sign in to the ZicNet panel, open the subscription area, copy the latest subscription link, and import it into Happ. If it was already imported, refresh the subscription so the app loads the new server list.

Paid but the panel does not show an active plan

If you paid but the panel does not show an active plan yet, confirm you are signed in to the correct account, reload the panel or sign out and back in, and avoid importing an old link. If the plan still does not appear, send a panel-status screenshot with email/ID hidden, transaction reference or payment time if available, payment channel, and device so support can check. Do not post payment details publicly.

I opened the panel but cannot find the subscription link

If you bought a plan but cannot see the subscription link in the panel, confirm you are signed in to the correct account, check that the plan is active, reload the panel, then open the subscription area again. Do not create a manual config; if the link is still missing, send a screenshot with private account details hidden and the purchase time.

Imported the link but Happ still uses old servers

If Happ accepted the link but still shows old servers or no change after purchase or renewal, tap refresh or update subscription in Happ. If it still does not change, remove the old subscription in Happ, copy the latest link from the ZicNet panel, and import again. Do not edit each server manually; if it still fails, send a screenshot with the subscription link hidden and the check time.

View the detailed guide

Importing many times created duplicate subscriptions or profiles

If Happ shows several similar subscriptions or profiles after repeated imports, keep one latest subscription from the panel, refresh or update it, then test Singapore or Japan. Remove old profiles only when you are sure they are old; do not edit each server manually. If unsure, send a list screenshot with the subscription link hidden.

View the detailed guide

Do I need to refresh after changing location or plan?

Yes. After changing a preferred location, changing plan, renewing, or support says the server list was updated, open Happ and refresh or update the subscription so the app loads the newest list. If old servers remain, copy the latest subscription link from the panel and import it again; do not edit each server by hand.

Empty server list after import

If Happ imports the link but shows no servers, refresh the subscription, confirm the plan is active in the panel, copy the latest link, and import again. If it stays empty, send a screenshot with the subscription link hidden, device, ISP, and issue time.

View the detailed guide

Bought a plan but not activated yet

Activation usually finishes when Happ has loaded the latest subscription link and connected at least once. After purchase, copy the link again from the panel, import or refresh it in Happ, choose Singapore or Japan first, and check the connected state.

View the detailed guide

How do I know Happ activation worked?

If Happ loaded the server list from the latest subscription link, shows connected, and 2-3 normal websites or apps open through the selected location, that device can be treated as activated. Keep note of the stable location, do not share the subscription link, and use the same latest link if you need to set up another device.

Changed device or reinstalled Happ and lost servers

A new device or freshly installed app does not automatically keep the old configuration. Install Happ, sign in to the correct ZicNet panel account, copy the latest subscription link, then import or refresh it in Happ. Do not rebuild the setup from old screenshots; if servers are still missing, send a screenshot with the subscription link hidden.

After updating Happ, servers disappear or connection fails

After updating Happ or installing a new version, the app may need to load the subscription again. Sign in to the correct ZicNet panel account, copy the latest subscription link, import or refresh it in Happ, allow VPN/network permission if the system asks, then try Singapore or Japan. If it still fails, send device, OS, Happ version if visible, and a screenshot with the subscription link hidden.

Choose Singapore, Japan, or US

If you are in Vietnam, try Singapore or Japan first. Test 2-3 locations under the same conditions and keep the most stable route.

I chose a location but an app or website shows another place

First confirm Happ is connected to the right profile/location, disconnect and choose the location again, refresh/update the subscription if the plan or server list just changed, and compare two different checking sources. Some apps or websites cache location or use IP-location databases that update slowly, so do not switch apps immediately. If it still looks wrong, send the selected location, the app/website that reports another place, ISP/Wi-Fi, device, and a screenshot with private data hidden.

Is Happ the app or the ZicNet service?

Happ is the third-party client app used to import the subscription link and connect. ZicNet is the service that sells plans, manages accounts, and provides the subscription link through the panel.

What should you send for faster support?

A useful support request helps the technician reproduce the issue. Instead of only saying that it does not connect, include the device, app, tested location, ISP, screenshot, and issue time. If the issue appears only on one Wi-Fi network or one SIM card, include that detail because routing often changes by ISP and peak-hour timing.

Device and app

Tell support whether you use Android, iOS, Windows, or macOS, plus the Happ version if visible.

Error screenshot

A screenshot helps separate VPN permission, import, subscription, and route connection issues.

ISP and time

Routing can change by ISP and peak hours, so the time of issue is useful diagnostic context.
