Dear All,

I'd like to set up an OPC UA server with a node 'OPC UA server' from node-red-contrib-opcua.  
I just set 53880 to the port number and deployed it.  
But, status indicator below the node shows 'Not running'.  
I cannot image how to investigate its reason anymore.

If you have any comments on the above, I would really appreciate it.  
Best regards,

Use another port, it can be reserved/allocated or windows has not freed it.
