Folder stopped syncing, trouble re-creating folder pair sync

Support
1

I set up the folders I want to sync across two machines (both MX Linux operating system). It worked for a while then I noticed “Out of Sync” errors on the WebGUI. I need them to sync with each machine at a different location behind NAT firewalls, so I chose syncthing. Only one folder is giving me trouble at the moment that I know of, so I removed the folder(only on syncthing, no file deletions) from one side, stopped sharing on the other side and tried to reshare. I can’t seem to fix this share and get it to start working again, so I’d appreciate any help. Here’s what I get in the logs:

How was Syncthing installed and how is it started?

I start it in KDE Autostart, and if for some reason it’s not started, I use GUI to restart daemon and get this error:

That particular error message is part of Syncthing’s collection of data safety features. It’s designed to reduce the chances of a user inadvertently wiping out their files.

Syncthing is checking for the existence of /home/networkr/Downloads/.stfolder. The safest solution is to remove the Syncthing folder (e.g. via Syncthing’s web GUI) and re-add it again (Syncthing will recreate its marker folder).

According to the log entries you posted earlier, you’ve also got a permissions issue with your /home/networkr/Downloads directory. It’s the reason why I asked how Syncthing was installed and how it’s being started because it can complicate managing permissions.
