That means that the session (TCP/TLS) has timed out, but the phone
continues sending DTLS UDP packets and expecting the server to reply.
There is not much the server can do, as the session's credentials no
longer exist. What you could do is try to play with the various
timeout values in the server's configuration and see which one fits
your mobile better. In that case let us know.

I think the best suggestion is to use the openconnect android application.
