Using serveo in Russia

[A E]

Command   ssh -R site-andrew-local:80:localhost:80 serveo.net don't work in Russia.

Are there any restrictions on working in the Russian Federation?

Blocking everything, huh? Perhaps it is necessary in order to avoid western propaganda in difficult times. Anyway, guess that you could -maybe- try to disable IPv6 (certainly, in any case) and skip via something like the Proton VPN; and see what happens? Not sure what can, even, work.
