Good news, we root-caused and (hopefully) fixed the issue with the connection stopping after a while. This will be pushed with the next Beta sometime later this week (we are holding back for the 1.11 release).
We also hopefully fixed a number of other networking related issues, though we were unable to reproduce some of the issues reported in this thread and elsewhere. For these cases we have hopefully improved our data collection should these issues occur, which should help with the debug.
Apologies for the issues and many thanks for the feedback and help in debugging them
