Hi, try
ssh -vvv <user>@<host> to get more information about the problem.

Check the log files an the server itself maybe /var/log/messages..


Good luck

That account (user id) might be expired, check using the following command

# chage -l  userid

Use 'man chage' for more info.

If the connection is being established, consult /var/log/auth* or /var/log/secure* for details.

For most of the service account, they are configured with no login shell, when you are trying to have a remote login, that is why it creates problem. Assign a login shell for that user account and then retry.

Thanks.
