the log line doesn't give me a lot to work with, but its unique enough that I could track it to the bundle keys of that msg which are combination of InstallStep_InstallUnsuccessful_Text and InstallSupportImpl_TurnOnTimeout. 

I don't think this is about URL connections, since the timeout is set to 30s by default, so it can only be
https://github.com/apache/netbeans/blob/b5d2a9b2be0ac90b098cc8ba553416f71f8cbf4c/platform/autoupdate.services/src/org/netbeans/modules/autoupdate/services/InstallSupportImpl.java#L417-L433

This section expects module loading to happen within a certain amount of time. If it doesn't, it gives up and assumes the module didn't load - which sounds like a pretty good assumption since the timeout is 10s per module.

I am sure the log has far more information when that happens.

michael
