What end-user system are you using? Windows? Linux?
The AP just copies EAP packets between the end-user system and the RADIUS server. The AP doesn't have anything to do with the EAP methods.

This is a magically unhelpful error from OpenSSL. There are many reason why it could happen. All of these reasons are related to TLS negotiation and/or certificate issues.

Then the issue is the end-user system.
You can't debug an end-user system by looking at the RADIUS server. It's looking in entirely the wrong place. The RADIUS server is just telling you what the error is. The RADIUS server isn't *creating* the error.
