Trying to SSH to a vCenter, and the connection fails.

Run the Command-Line Interface (CLI) command to try and manually start the SSH service.
systemctl start sshd
Cause
The sshd configuration file is corrupt:
Resolution
Run the command below to check the configuration files. If the output shows any error, open the configuration file to check the related information.
