Several different, random seeming files across various different Syncthing folders keep failing to sync even after restart, rescan, and reconfiguration, with the below error
syncing: finishing: opening temp file: open /storage/emulated/0/Pictures/Webcam/.syncthing.2024-07-1621:42:30.jpg.tmp: operation not permitted
I don’t how how to fix it, the desktop app has the required permissions, and the Android app has as many storage permissions as I can give it under Android’s horrible SAF limitations.
It seemed to used to be happening only to some specific old files, but now it’s happening to all the new files I add onto my laptop under Videos or Music.
In addition, when trying to sync files with a specific server, it shows as disconnected, even when both are online and connected to the LAN (my phone via WiFi, the server via Ethernet), and there is some error about encryption expectations

The server is running Syncthing GUI on Fedora GNOME, same as the laptop (which does work besides for the first issue), so I don’t know what the difference is that would be causing this, not a single file has been synced to the server.
This is honestly making me want to get a Fairphone 5 with Ubuntu touch to get rid of these issues, but I can’t do that now.
If anyone could advise, I would really appreciate it!
Are you starting the server and laptop Syncthings as systemd user units? You’ll see stuff asking for ‘systemctl status syncthing@yourusername’ if you are. That way it works (and has worked for years now) for me. I’ve kept the config really simple because I only have it syncing at home, so no encryption or discovery. If you also only have it working on a trusted network, maybe ditch the complications…?
The Android side is tough because of all the restrictions. I’d imagine that’s what is troubling your phone Syncthing.
It’s not running with the command line. On the laptop side though, the WebUI shows no errors, and the WebUI on the phone shoes multiple errors with tmp files that don’t actually exist in either the laptop of phone’s filesystem.
