Can't get remote device to connect

Have it installed on two machines, a local and a remote one.

Each has the other added and I have a folder with the same folder ID on both. But the remote devices always shows Disconnected.

On the remote device logs show:

019-07-12 02:25:06 Listen (BEP/tcp): listen tcp :51684: bind: address already in use 2019-07-12 02:25:06 Entering the backoff state. 2019-07-12 02:25:06 c.S.listenerSupervisor: Failed service ‘tcp://:51684’ (2.999994 failures of 2.000000), restarting: false, error: “{tcp://:51684 tcp://:51684} returned unexpectedly”, stacktrace: [unknown stack trace]

On my local device, logs:

2019-07-11 19:33:25 Relay listener (dynamic+https://relays.syncthing.net/endpoint) shutting down 2019-07-11 19:33:25 Entering the backoff state. 2019-07-11 19:33:25 c.S.listenerSupervisor: Failed service ‘dynamic+https://relays.syncthing.net/endpoint’ (2.889828 failures of 2.000000), restarting: false, error: “{dynamic+https://relays.syncthing.net/endpoint dynamic+https://relays.syncthing.net/endpoint} returned unexpectedly”, stacktrace: [unknown stack trace] 2019-07-11 19:33:26 Detected 1 NAT servic

So Syncthing did not like being set to host under Unraids Docker system. Fixed right up when I gave it its own IP address.
