    Hallo h-hermsen, thank you very much for yuor help. You mean that I should change the name into the ip(opc.tcp://192.168.1.108:4840). I have done in Server Settings as the first screenshot in the added attachment. Is that right? But I still can not connect UaExpert to OPCUA Server on Raspberry Pi and I get new error message as the second screenshot in the added attachment. Can you help me? This is very important for my work. Please... BR leon-zhang
