I have two devices. Sometimes when it is downloading/syncing a file it would just randomly stop midway. The download speed shows 0 bps/kbps. I have to constantly restart syncthing on either end (mostly the recieving end) for it continue syncing, sometimes restarting would not fix the problem.
Here are some screenshots of the problem.
I have already reinstalled syncthing on both devices with no effect. I have also moved the receiving folder to an SSD, believing it would be a faulty hard drive, no difference.
As of creating this post the sync managed to complete after around an hour, which I believe should not happen.
