Hi!
I upgraded from Clearpass 6.9 to 6.12 last month. Everything worked fine, as expected. But we've had a few cases where Windows 11 BYOD devices can't log on to our 802.1x SSID.
The access log says: RADIUS EAP: Client doesn't support configured EAP methods
The BYOD devices that were already connected before the upgrade, could still connect.
Haven't bothered to much about it untill today, where lots of googling and trial and error turned me to TLS1.3. When I dsabled TLS1.3 from Cluster Wide Settings, they connect again just fine.
But I fail to see why? If CPPM now support TLS1.3, why can't my Windows 11 clients connect? I'm sure there's an easy explanation, but I can't see it.
This link is a bit dubious, though. https://www.arubanetworks.com/techdocs/ClearPass/6.12/PolicyManager/Content/CPPM_UserGuide/Cipher Suites/Ciphers_TLS.htm
Thanks.
