Open Happ and use the standard shutdown action. Wait for the interface to show an inactive state. Then, close the app completely and start it again without turning on the connection.
If the app freezes or doesn't respond, terminate it with a normal operating system tool. Do not delete local data and configurations at this point.
Check the regular internet
Open a few sites and another app. If the network is not working on all devices, the problem may be with the router or ISP, and not with the local Happ settings. If only one device is left without the Internet, continue local diagnostics.
Reconnect to Wi-Fi or turn your mobile data off and on again. This is safer than a full network reset.
Check the system proxy
On desktop systems, after a network application crashes, the system proxy sometimes remains in an altered state. Open the standard proxy settings of the operating system and compare them with the state before starting Happ. If you don't know the original values, don't enter random addresses and ports.
Disable only a setting that clearly refers to a completed local connection and has been enabled by Happ. Take a screenshot of the original state before changing so that the settings can be reverted.
Check your network adapter or TUN
If TUN was used, make sure that the virtual network component did not remain active after the application was closed. First, restart Happ and perform the standard power on and off. Then restart your device.
Do not manually uninstall drivers without a confirmed version-specific instruction. In the official release of Happ Desktop 3.1.0, the developers separately announced a fix for sleep recovery, in which the Internet could remain blocked until a reboot. Therefore, the app version is important for diagnostics.
Get the DNS back up and running
If the DNS has changed in Happ or in the system profile, return the last working value. Don't install a third-party DNS just because it's mentioned in a random instruction: first, you need to confirm that the problem is really related to domain name resolution.
After the change, close your browser, open it again, and check a few different sites.
Secure recovery procedure
- Disable Happ normally.
- Close the app completely.
- Reconnect to your current network.
- Check the system proxy.
- Restart your device.
- Check the internet before restarting Happ.
- Only after the network is restored turn the app back on.
If the Internet is lost again with each disconnection, record the connection mode and the exact action after which the problem occurs.
If it doesn't help
Do not perform a full network reset until you have saved the required Wi-Fi settings and checked the impact on your device. Prepare Happ version, OS, mode used, crash time, and screenshots of system settings without personal data.
Contact the Happ Plus support and attach an impersonal log. If the problem appears already when the connection is active, use the instructions "After connecting Happ, the Internet disappears".
Consider reinstalling only after these checks and retain access to Happ Safe Reinstallation Instructions.
Frequently Asked Questions
Will a reboot help?
It can restore the temporarily remaining network component, but it is also important to fix the version and mode so that the problem does not recur without explanation.
Do I need to uninstall the TAN driver?
No, not the first step. First, use a regular shutdown, restart of the Happ and the device. Manual removal requires a separate, proven instruction.
Why can't the network be reset immediately?
A hard reset removes other saved settings and makes it difficult to determine the cause. Start with reversible actions.
