When trying to create a new OPC connection after inserting the endpoint URL and clicking "Next" i get a Internal Error.

The opc server is created locally on the computer via a python script. I have no issue when trying to connect to the OPC server via an windows 10 pc, but when trying connect to the server on my windows 11 pc the "Internal Error" message appears. Please help.

After uninstalling and deleting all files regarding ignition and Inductive Automation and reinstalling everything again the "Internal Error" message did not appear. Now I could create the new connection! Simple fix but worked.
