I also can't connect on configuring it from scratch (tweaking IPv6 option does not help (I don't have IPv6)):

It seems, the problem is with libgiolibproxy.so:

This absolutely doesn't mean it's the cause.

Most likely the connection is just blocked by provider or firewall

II checked on PC without a firewall. The PC is connected to phone WiFi hotspot and on the phone itself Telegram does work. So the problem is in Telegram Desktop, not provider.

I can't confirm 🤷‍♂️
