I am experiencing numerous connection timeouts as of today.
Both websites are using Apache, and it is worth noting that I do NOT get timeouts when accessing member.rail-record.co.uk from browser. My PHP settings for member.rail-record.co.uk - the site that is timing out on remote connections via SSH and fsockopen - can be found at https://member.rail-record.co.uk/php-info.php
I recently upgraded the server to a Intel 4gb 2cpu last weekend. The site was working fine up until today and nothing has since changed as far as I am aware.
I have attempted to diagnose the problem in a number of ways.
But even with the above, that shouldnt cause the sluggishness and timeouts when using the SSH?
Does any one have any recommendations as to what I can do about this?
Here’s some more information.
At 10:26, I triggered the timeout. But nothing in mysql error log for 10:26, only an earlier timeout:

There are a number of lines in UFW along the lines of the below (although not excessive, maybe a few per minute), but as I mentioned, disabling UFW has no effect and nothing about my live server IP / origin requesting server

Guessing no point checking apache logs as site accessible fine, just external connections.
I have a user set up on mysql for the remote site, and I am binding address etc in my.cnf. Like I said, everything fine until today.
Does anyone have any suggestions of what else to check, to help diagnose the issue?
