Cannot able to connect to node-red. How should i tackle this?
I am pasting my cmd screenshot
There is no node-red to connect to - it was crashed by a mis-behaving node
Something to do with node-opcua
You should identify the node & report this to the author. In short, if a node does not handle its own errors correctly, it can crash node-red.
You can report the problem by raising an issue on the repository. You can (usually) find the repository by visiting the flows library (linked above)
Lastly, start node-red in safe mode & either fix up or remove the bad node, then deploy.
To start node-red in safe mode, see the command line usage
