Dropbox Cloud Sync - Everything disappears

OS: Windows 10 x64 enterprise
PMS: Version 1.3.4.3285
Browser: Chrome Version 55.0.2883.87 m

I use the cloud sync functionality with Dropbox. I have been using it for years and no issues. Dropbox has plenty of available space.

I have one library, called Bob’s Tv Shows.

Starting last night, when I access Bob’s TV shows, via the cloud sync, I can see all of the tv shows. If I click on the show, I see the season I have uploaded (screen shot 1). When I click on the season, nothing is there (screen shot 2). This is the same thing for every show.

I can see and play locally, ie not from the cloud sync folder.

I have tested a Roku 3, Android tablet, and Android Phone. All show the tv shows, but nothing inside once I go into it. I have about 5 shows and a season in each.

When I go into my sync settings I can see the library is synced (screen shot 3).
Here are my cloud sync settings. (screen shot 4).

Within the last 30 days, i deleted everything from the cloud sync. I spent the time re-uploading. It “seemed” like everything was working as expected. Went to bed last night, woke up this morning and everything in the cloud sync is gone. It is all there locally, but literally nothing in the cloud.

How can I trouble shoot this issue? What log can i look at? I really can’t keep deleting and uploading again. 5 shows x 15 episodes in each x 1.5gb per show…this is just way to much time and bandwidth to deal with.

Here are my log files.

Help! I just don’t know how to fix this. Thank you!

Since this issue keeps repeating itself every couple weeks, could anyone help me to trouble shoot the issue? What logs should I look at? Anything to point me in the right direction would be awesome. It is really frustrating to have to re-upload all my files into Dropbox every couple weeks.

Ok. I wiped everything and started over. This is the 3rd time now. Added a new tv show today and boom…all of a sudden…everything has stopped working again.

Here are two file. File one is just the errors found in all of the log files. File 2 is all log files.

Any help would be awesome. This is getting soooo frustrating.

Here is the log from the CloudServer as well. I enabled verbose logging, then attempted to access a library.
