Hostname turns into server internal name

If you're unsure what's being sent back from the backend, run a tcpdump from the command line, and capture to a file (-w option), grabbing the full packet (-s 0 == don't truncate the snap) and then peruse the response either via tcpdump, or if you're more desktop orientated using something like wireshark

Often seeing exactly what is coming back can be a good hint as to why it's doing that
