I just installed Syncthing on Debian 10 and in ssh command line typed syncthing
It looked like it was about to start up but stopped after joining a relay. The Gui never launched.
This is a remote VPS on Vultr.

There’s no indication that it stopped. It’s listening on localhost, so unless you forward that port you wont be able to access the UI from another system. You’d need to change the listening address and setup the GUI then.
As soon as you log out, that will not run anymore. Use a service manager if you want to run it consistently.
