I’ve got Syncthing installed on my Synology NAS (through the package manager), as well as a few Windows machines and an Android device. Things have been working pretty smoothly, but recently the Synology device seems to only briefly connect to the other devices, sometimes remaining disconnected for days at a time.
All of the addresses are configured as dynamic for the Windows machines and the Android device. The issue seems to be limited to the Synology install… all other clients go 2-4 days without contacting it. They will randomly connect every once in a while, which makes it difficult to think it is a configuration issue. I haven’t made any firewall changes on my network recently, so I’m not sure why this issue has cropped up. What is the best way to find out why the devices aren’t connecting?
