SSL Certificate invalid for specific pages only (6 replies)

Further to the post at [forum.wampserver.com], I'm running into an odd situation where I've upgraded my WAMP (WAMP 3.3.1, Apache 2.4.55.2, PHP 8.1.16, WAMP Icon is green). Upgrades were done in 1 week stages to ensure nothing broke in the web app, and the last phase was Thursday where I upgraded PHP, MariaDB (10.1 to 10.11.2 and the web app itself. Everything worked fine (I thought) but then we started seeing specific users unable to access specific projects in the website. The error log is saying "server certificate does NOT include an ID which matches the server name".

Login page, Main page, and vast majority of projects are all accessible and work. Only specific projects are not working.

This was not happening on the previous version (WAMP 3.1.0, Apache 2.4.27, PHP 7.1.9) so I'm not sure what happened.

1 - Windows version used (Specify version number AND whether 32 or 64 bit) - Windows 2019 64 bit
2 - Version WampServer (Specify version number AND whether 32 or 64 bit) - WAMP 3.3.1 64 bit
3 - Apache Version - 2.4.55.2
4 - PHP Version - 8.1.16
5 - MySQL Version - N/A
5a - MariaDB version if applicable - N/A (running on a different server, but running 10.11.2)
6 - What color is the WampServer icon (in the notification area of the taskbar) - Green
