Thanks Aravinda!
The problem was in duplicate keys in authorized_keys file, one with prefix “command=“ the other one is exactly the same key but with prefix ssh-rsa.
I’ve removed the one with prefix ssh-rsa, and the session is now working fine :D
I’ll do some failure tests then I’ll update you with the results.
