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 did not ask you for link but for steps you did. Moreover this howto might be obsolete because "openssl pkcs12" with openssl3.0 sometimes needs "-legacy" option i.e. openssl pkcs12 -legacy -export -in ... -certfile ...-inkey ... -out ...
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.
Tested now: TCL NXT paper - (Android 11) - no such thing happened, after "forgetting" connection certificates remains, and can be used to redefine connection. As Alan said: either you do something wrong (this is my susppect) or you found SERIOUS bug in android supplicant (I doubt) KJ
