Hi, This OPC UA client node just suddenly cannot take in value from the server anymore, as mentioned in the error message, the max message has been exceeded. How can i remove and add the new socket for this OPCUA client node? Or is this not the ideal way of solving this problem?

Do you have a license issue? Maybe on the OPC server side??

If you exceed session count then use one client node and send needed action inside msg.payload.action

If server is node-red node then there is message size inside server-node as a parameter.
