strongSwan requests XAuth authentication from the client, but the client
does not seem to answer. Either it does not get the message, the user is
not entering the credentials in time, or more likely, it does not expect
an XAuth username/password request.

Most likely your client is not configured to do XAuth, or it is one of
those clients that want to skip XAuth authentication during the ISAKMP
reauthentication procedure (iOS, OS X). We strictly require that, as we
think just skipping XAuth is a security issue.
