[Solved] Matter and Thread Issues with 2025.4.0 and 4.1

I have started a github to track and provide details with current issues I am facing with Thread and Matter over wifi since updating to 2025.4.0 and 4.1.

Figured I would link it here as well to get more eyes on the issue to see what is happening to get this resolved:

The short of it is that my border router is not showing up whilst configuration changes are able to be pushed to it via HA and the matter integration is forgetting the IP’s of the commissioned devices until removed and re-commissioned.

Not to mention that the open thread border router addon crashes at startup.

edit: turns out root issue was security settings in network switch, specific setting will be listed in thread linked once I go through the list to validate which one caused it.
