It appeared to be not only an upgrade to PHP8.1 but also a change in IP address where the alias for the hostname was removed from the server. Changed the config to connect to localhost:22 now and it’s back working. Thanks for your support. Case closed.

Btw, if we are setting up the connection from external then what site is it as it will be blocked if not explicitly whitelisted.

We are coming from version PHP 7.x, not 8.0. It’s still not working where I now see the below error message when trying to update to latest version of WP:

Notice: Cannot connect to xxx.yyy.com:22. Error 60. Operation timed out in /usr/home/renek/public_html/wp-content/plugins/ssh-sftp-updater-support/phpseclib/Net/SSH2.php on line 1201

Strangely enough nothing was changed on the SSH IP whitelisting when the update to 8.1 was performed where it was working before just fine and it is not working any longer. It seems obvious that a connection is blocked somehow.
Can you tell me who is initiating the connection to our server? I hope it is not some external client using our credentials trying to setup a connection to our server?? Is it from localhost? Please can you give some more context?
