Hi all, I am trying to connect to OPC UA Simulator (see attached screenshot) in my UMH core instance. I am getting an error (see attached screenshot 2). How should I address this error? https://cdn.discordapp.com/attachments/984083100520808478/1417171289239453736/image.png?ex=68c9831d&is=68c8319d&hm=0b6b5780f291d31505459ffebc222dcae4c2bd5e12beb08d2588f632b7366e26& https://cdn.discordapp.com/attachments/984083100520808478/1417171289608556584/image.png?ex=68c9831d&is=68c8319d&hm=152b77f3fdc798f3f4f7094d31e2d668c79952d197753f93e4e673211c959408&

I guess you are using umh-core with the old documentation for UMH classic. The umh-core docs is here: https://docs.umh.app/ UMH core does not include a simulator anymore

Understood, thanks!

prosys simulation server

Good point!

Thanks for the idea. I downloaded Prosys and set it up. Now when I try to create a bridge with the given IP and port, it still shows me the same error https://cdn.discordapp.com/attachments/1417171289894027284/1417454959657750600/image.png?ex=68ca8b4d&is=68c939cd&hm=44615bec83a0a84d3ee88bd258fbb5765c40e22651a51c565831e7b137d5a275&

Have you configured the IP and Port correctly in the connection?

Connection address: opc.tcp://LAPTOP-4KO5N4R9.fritz.box:53530/OPCUA/SimulationServer Port: 53530 This is what I am getting from prosys, so i copied the same into the management console

try using the ip instead. is the simulator running on the same pc as umh ?

what @runeston3 said

Yes, the simulator is runnign on the same PC as UMH - simulator running in my windows and UMH hosted on a docker in docker desktop. Tried using the ip, same issue

it could also be localhost as "IP"

understood, I can try that

disable firewalls & use ua expert or prosys opcua browser to test if the serverside works

try "opc.tcp://127.0.0.1:53530/"
