One, don’t trust the built-in troubleshooter completely right now. It always spits out a key ports error even if you’re in the clear due to a oversight with patching that’ll be fixed with the new set of patches coming with WLM 2009 support for all clients.
Two, from the looks of it you’re connecting from Russia? Someone else had a similar problem (they’re from Crimea) and it turns out Google Cloud servers (that’s what Escargot is run from) are blocked in some regions (hopefully not all) of Russia over some stupid beef regarding Telegram. Not sure if those bans are in place nowadays, but you can always open a command prompt and run
tracert -h 100 escargot.log1p.xyz on it. If the last few hops fail, that probably means the servers are blocked and as for solutions the most I can come up with is a VPN.
