Setup Kepware on its own server, Ignition recognized it and I trusted the connection in Kepware. But Ignition gives this error.

Have you trusted the Kepware certificate on the Ignition side as well?

Thanks for the quick reply. No, I don’t know how to trust it on the Ignition side. I just stepped through the OPC-UA set up with the end point and it showed up on the Kepware side. How do I trust Kepware on the Ignition side?

Sounds like you’re somewhere around step 11.
