I haven't come across this exact error message yet. What I can say is
that it is unusual - a "simple" cert rejection would be logged on the
RADIUS side with a clear error message indicating that the client does
not like the server cert, not an "internal error".

A shot into the blue: is your server using (only) newest TLS versions?
And is the client Android maybe a rather old version? Sometimes TLS
versions from the future confuse clients from the past. :-)

In any case, from the looks of it this seems to be an interop issue CAT
can not do much about. Can you detail which device or Android version
this is?

Greetings,

Stefan Winter
