This combination of ap_scan=0 and WPA-EAP is unlikely to work. However,
based on the debug log, I would guess that you are actually not using
WPA at all. Removing that WPA-EAP from here would make the config file
easier to understand..

This phase2 line here is causing the connection to fail. autheap=PAP is
invalid option and removing it may make this actually work.. Now,
wpa_supplicant assumes that you want to use another EAP method in
Phase2, but in practice, I would assume you want to do PAP. In other
word,s change this to phase2="auth=PAP".

Please note that WPA needs to get WPA IE set correctly for the
association request and using ap_scan=0 is unlikely to work for that.
ap_scan=2 might, but it depends on whether the driver supports such
configuration. Anyway, it looks like you are not using WPA, so this
should not matter for now.

This is the part where wpa_supplicant gets confused about the phase2
configuration. It ends up believe that you want EAP and since there is
no EAP-PAP, it just default to allow all EAP methods that have been
marked available for phase 2 use.

This does not match wuith your configuration file example, i.e., I would
assume you had the phase1 line actually uncommented when producing this

So TLS part was completed without problems.

wpa_supplicant tries to start EAP in phase 2..

But authentication server does not like it.. I would assume it was
configured to accept only PAP.
