Why does Happ show a format error?
The link is often pasted into the wrong section. Use subscription URL import.

Happ VPN does not work: what to check
If Happ does not import the link or connection gives no site access, start with subscription format, DNS and other VPN conflicts.
Typical issues
a single vless:// profile was pasted instead of subscription URL
Private DNS breaks routing
Android keeps an old VPN permission state
the Wi-Fi provider filters the current route
What to do
1
Copy the WersidePN link again and import it as a subscription.
2
Disable Private DNS and other VPN apps.
3
Restart Happ and refresh the profile.
4
Check connection on mobile data.
Common questions
Can I replace Happ with V2RayTun?
Yes. The same WersidePN subscription link can be imported into another compatible client.
