Para mim, o problema foi uma chave incorreta em known_hosts
:
Quando tentei acessar o SSH no servidor, recebi:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
SHA256:<something>
Please contact your system administrator.
Add correct host key in /Users/myuser/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /Users/myuser/.ssh/known_hosts:86
RSA host key for <server> has changed and you have requested strict checking.
Host key verification failed.
A remoção da chave incorreta (desde que você confie no servidor) resolveu o problema.
