Frequent cloud storage authentication errors with Subsurface 4.5.6 (desktop)

[Miika Turkia]

I have encountered auth failure quite frequently with poor network connection. At home this has worked fine for me, so I suspect this is related to packet drop and long ttl.

I also got an infinite hang during a save. I'll take a look at a  back trace I got from that after my Subsurface testing session is over.It was on a select in libgit, so might be something that needs to be fixed there, or maybe we can have a timeout somewhere ourselves.

Having poor network here has really proven that this is not handled well at all. Will need to simulate it at home when I have more time to look at the code.

Is anyone else frequently seeing the following error when saving changes?

Authentication to cloud storage failed.
Cannot sync with cloud server, working with offline copy.

While this sometimes seems to be legitimate, often the error is displayed even though the changes appear to have been saved successfully. For example I'll change the Notes text for a recent dive and save (File -> Save), which triggers the error. I then look it up my dives on https://cloud.subsurface-divelog.org, and (frequently, but not always) find that the changed text is indeed present. Attempting to save multiple times in a row or choosing "Save to cloud storage" will sometimes complete without error, but it's very inconsistent.

This has been going on for awhile but I'd been assuming it was an issue with my home network, or notebook installation... I'm running Ubuntu 16.04 (Xenial), with Subsurface installed from the PPA. However I recently upgraded Subsurface (from either 4.5.2 or 4.5.3, IIRC) on my sister's macbook while we were visiting family, and she encountered the same stream of errors when saving her first new dive... we ended up trying to save about 4 times, before being confident all was well. Since the notebook, OS, and network were all different, I now believe this to be a more general issue.

Any idea how I can help to troubleshooting the issue? I'm happy to do whatever I can, but am not really sure where to begin.

Thanx!
