Hi

I am trying to connect to B&R OPC/UA server using ua expert from my windows 10 pc. I am using the correct IP address and port number. But every time I try to connect it says bad communication error. The server is in the local network. How can I diagnose this issue.?

Hi,

Did this issue get resolved. I am facing a similar issue with my connection. Anyone who can help me.

—Thanks

Hi,

I am also having a bad communication error while trying to connect with my OPC UA Server on a S7 1500. The IP address ist set and the server is activated. The client certificates are being accepted automatically so this should not be the problem. Could someone help with this error?
