Node-RED Refused to Connect

I'm having a problem with node-red, i can't start it anymore, every time i try to start it i get error: refused to connect, i am using an iot2050,
if anyone can please help me.
thank you.

The device with IP 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.

Thank You.

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.
