> Hi guys,
> I hope this issue doesn't exist (couldn't find similar).
> I have a problem with Guacamole 1.4.0 and SSH.
> On some Linux hosts I'm using SSH with 2FA (password + Google Authenticator or most frequently publickey + Google Authenticator).
> Guacamole asks for password or passphrase when we connect to SSH then fails with "Log in failed. Please reconnect and try again".
> It never asks for verification code.
> In log files :
> {code:java}
> Public key authentication failed: Invalid signature for supplied public key, or bad username/public key combination
> ERROR:        Public key authentication failed: Invalid signature for supplied public key, or bad username/public key combination {code}
> I've checked in documentation, mailing list and Jira but couldn't find an answer.
> Is there a way to get 2FA working with SSH connections ?
> Thanks for your help and congrats for this amazing tool.
