Do not try session resumption after EAP failure

Browse source 
If session resumption fails for any reason, do not try it again because
that is just likely to fail. Instead, drop back to using full
authentication which may work. This is a workaround for servers that do
not like session resumption, but do not know how to fall back to full
authentication properly.
