The imported socket library seems returning often unexpected values, therefore the script stops in most cases.
So either a proper handling of the returned types has to be included or perhaps the version of socket changed.
But it seems socket is often not only returning "unexpected" but also unreasonable values - in other words wrong values, so it might be considerable to replace it completely if another version never returns better results. A reason for wrong return-values could be that parameters are used wrong, that should be checked before planning further steps.
