i´m trying to connect my PLC over the Client with Node-RED.
i added in my Client a Server with the correct address (hopefully )but i receive this error " Client node error on: error: [" OPC UA connection error: End point must exist opc.tcp://139.6.134.110:4840"]".
when i Change somthing on my PLC changes the value on Client, which means they are connected, but i can't connect my Client with Node-RED.
that looks to be connected correctly
i copied my OPC URL from my Client, everythings looks good, but when i use OPCUA-Client in Node-RED i receive the errors
