My Wi-Fi uses 802.1x EAP with TLS. It works well with the old Android devices, but an Android 10 device pretends that it's trying to connect, and a few seconds later marks the connection as disabled. There is absolutely nothing in the Radius logs about any failed connection attempt.
The configuration is quite the same between this device and the older ones, with two differences:
Security field is unavailable, unless I chose to manually add the network, in which case there is no “802.1x EAP,” but only “WEP,” “WPA/WPA2-Personal” and “WPA/WPA2/WPA3-Enterprise.” I suppose that I need to chose the last one.
Domain field is added between CA Certificate and User certificate. I tried to keep it empty or enter the domain name of the company; the result is the same.
What can I do to understand why doesn't the device attempt to talk to the Radius server before marking the connection as disabled?
