I have installed syncthing on a Debian 11 VPS. It’s similar to another syncthing installation I have on a Ubuntu 20/04 VPS. However this syncthing shuts itself down after a few hours. If I log back into the server it seems to wake up but I’d much prefer it to keep running all the time.
The VPS is on fasthosts.co.uk, I can’t see anything strange about their VPS’s?
