Resolved SSH root public key stopped working

[jimlongo56]

Since I last logged in to my Plesk Onyx 17.8 via ssh my key has stopped working (probably a month or more ago, this is a dev server).

This is a key from my local computer.
I want to SSH to my Plesk server as root.
The public key is uploaded to the plesk server in

~/.ssh/authorized_keys

Permissions seem correct

[root@li505-108 ~]# ls -la ~/.ssh/authorized_keys
-rw------- 1 root root 411 Sep 24 13:53 /root/.ssh/authorized_keys

from my local machine this times out . . .

ssh root@xx.175.208.108 -p 22022 -i ~/.ssh/mini_rsa

This key works currently on many other servers, so it's not that, and my local .ssh/config is normally setup to use this port and key for this server.

Solved: Port was blocked.

Changing /etc/ssh/sshd_config back to Port 22 let me in via the key.

Re-open the port in the Firewall.

iptables -I INPUT -p tcp --dport 22022 -m state --state NEW -j ACCEPT

Change sshd_config back to Port 22022, and it worked.
