SSH Remote Login Not Working Anymore!

[kisong]

For several months, I was able to login to my ssh account without any problems. I changed the default port to xxxx (do not want to reveal this port for security reasons).

Anyways, a couple days ago, I restarted my server, and now, I am unable to login to the SSH server. I am 100% sure I am connecting to the right port and ip address. I am also sure that the port is open to connections. I know this because I can go to to a port scanning site and it says that the ssh port is open.

I checked the sshd_config settings and the correct port is open.

What other settings should I check?
