Recently, running a cloud sync task to backblaze has become unresponsive. I also cannot edit a cloud sync task because the edit window will display the circular "loading" icon and never let me edit the details. This happens on both Chrome and Firefox browsers, and survives a reboot.
As for the unresponsive cloud sync tasks, both dry run tests and syncs hang, or only partially finish. I have seen some "broken pipe" errors, but usually never get any failure messages. They simply hang at a certain percent complete forever.
