eap_peap: ERROR: (TLS) Alert read:fatal:unknown CA

[Dario Barbon]

Hi Kamil, I generated the certificates by following this tutorial 
("configure EAP-TLS" section): 
https://techtalkblog.ch/ubuntu-18-04-freeradius-v3-wifi-authentication/

I'm not thinking that certificates are deleted ... I saw this happens 
many times! And it happens (in my limited experience) always with 
Android 11 devices.

Sometimes users deleted the WiFi connection: that action deletes also 
WiFi user installed certificates. Sometimes, after a bunch of 
unsuccessful connection tries, Android 11 devices deletes certificates.

In comparison with Android 12 devices that retains certificates but 
required to switch off/on WiFi to successfully reconnect.
