Happ and INCY are free apps: you do not pay the app, you pay the service whose subscription you add to it. How to choose a service, what you can pay for Tainet with, how to pay without Telegram and try it without a card.
Why Happ shows "Xray core critical error" or a core start error on PC, "Timeout", "Subscription expired" or a TLS error. A symptom-by-symptom guide: what each error means and how to clear it.
Where to download Happ for your computer, which file to pick for Windows and Mac, how to add a subscription, how TUN mode differs from proxy mode, and what to do when the Happ service won't start.
What a VPN key really is, in plain words: why the key, the config and the subscription link are the same thing, where Happ keys come from, why free keys stop working, and where to paste the key.
Step-by-step Happ setup on iPhone, Android, Windows and TV: the subscription, picking a server - and fixes for when Happ isn't working or won't connect.
