The device with IP 10.137.1.20 is not reachable causing node-red to crash (most likely a specific node that tries to connect to it). You can start node-red: `node-red --safe` which will start it without the flows running. Then you can correct the flows by removing/updating the offending node (if possible) and then deploy, which will (re)start the flows.

If you find out what node is causing that, please do raise a GitHub issue against it because nodes should not cause Node-RED to crash.
