I've set up WireGuard on a VPS.

A client on Linux desktop works with no issues.

The one on an android phone too, but not completely. Namely, TX and RX get updated, "handshake" and "last connected" with a phone on a server gets updated too, as well as on a phone itself. However, I can't open any single website.

However, Telegram, for instance, works well. Another android app too, it appears. But all the rest of the apps don't, not do the Firefox and Chrome.

What's the matter?
