"No availabile source device" - sync is stuck #1628
Description
Me and a friend are sharing a folder. It worked fine for two weeks, now one file is stuck.
On my side the GUI says it's syncing 77% and that's not changing. No error messages.
The file is on my machine and the remote machine is unable to fetch it for some reason.
I have experienced numerous system crashes recently, maybe that could have caused the trouble?
I can remove that file, but it doesn't seem like a solution to me.
Here's a log from the friend's machine (I removed IPs, names and syncthing IDs):
