This was setup & tested about 3 weeks ago. Worked fine from home (inside home network, but also across mobile network.
Now on the road my Windows 11 laptop connects without any issue; using a website like What is My IP I can see all my traffic is first traveling to the VPN server a home, then onto the public internet. Also, certain video services that are only available in my home country wrok perfectly when the VPN is connected. All this is as expected.
Our Android devices however won't connect, below (and attached) the error messages we get on the devices.
I first though this might be a certificate issue so I replaced the Let's Encrypt certificate with a Sectigo certificate, generated a new profile, read that into the devices. Unfortunately, the Android devices still cannot connect. The Windows laptop works as expected.
Any idea how to resolve this?
Error messages:

Continue connecting without a certificate or select one from the Android keychain?
