RADIUS server 192.168.40.58:1812 failed to respond to request (ID 41) for client 56:61:55:3e:c2:e5 / user 'ThePlague'

I keep getting these errors when I am trying test test 802.1X I checked the firewall in the auth and accounting server and made a rule to allow inbound connections on port 1812-1813 i tried turning off the firewall and i checked my main firewall and there are no rules blocking it I dont know why i am getting it i double checked the secret and the ip addresses

If you don’t see logs, then the traffic is not reaching to NPS server. Make sure that the Windows FW is not blocking that traffic also.
A few questions, is this a new setup? Is this working for any other services? Have you tried to restart the NPS service or the box itself? From the NPS server, run a telnet to the controller ip using port 1812 and 1813 or from another device on the same subnet as the controller.

Another thing that could be making NPS not to log anything is a mismatch in the Shared Secret between WLC (or APs if you're using local atuh from Flexconnect APs) and NPS server.

A fix is a fix, but sometimes it's best to keep track of your changes, because usually it will happen again in the future.
