The problem can probably be solved either by the data center, though that's probably a lot of work, because they have to update the radius for TLS 1.3. New Windows 11 22h2 forces your device to connect via TLS 1.3 (although TLS 1.3. is like.. not even out yet). But you can change the registry, so it ain't gonna use 1.3. again by following these instructions:
Add this value to the registry (windows key + R, enter regedit...make the addition below to the specified directory) , then TLS <1.3 will be enforced:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\PPP\EAP\13]
"TLSVersion"=dword:00000fc0
