Hello, I installed docker desktop then I installed nodered. I used the following from NodeRed for this: docker run -it -p 1880:1880 -v node_red_data:/data --name mynodered nodered/node-red Now I want to set up OPCUA server. I installed the necessary pallets for this. node-red-comtrib-opcua node-red-contrib-opcua-server And this is the Flow (from Examples) [image] Everything looks good, the structure is obviously being built! so I try to connect to this OPCUA server using UA-Expert, but it doesn't work. [image] I used “localhost” for the IP address. Port remained the same "54845". For the IP address i also used "host.docker.internal" but unfortunately not successful either. I get this message all the time: BadCommunicationError Is it correct that I use "localhost" as IP address? If not, what else should I use? Thank you very much! Ahmad
