Linux Mint: syncthing launches with no visible error output but changes to unknown-device

Hello all, latest Linux Mint here and I am having a very odd problem where after I launch syncthing, and go to the webUI, a moment later it loses it’s own device name, changing from mint to “unknown device” and then it’s OWN device is listed in the remote devices now, in the bottom right corner

Help!

Have you cloned/copied your configuration (and the key files with it) by any chance? Alternatively, was there any restoration from backup involved?

It sounds like you’re using the same key files on two devices, which will not end well :sweat_smile:. This seems like a completely new installation, so I’d start with simply deleting both cert.pem and key.pem. Their location is dependent on the OS and also how you’ve installed Syncthing, but please check https://docs.syncthing.net/users/config for the default paths on Linux.

I don’t know why this happens, but I experienced it a few days ago, and refreshing the web GUI and waiting fixed it.
