​​​​​​​Hello @DM 
I am facing some difficulty with the ControlBuild 20x OPC UA Connector with my project.
I would like to connect to the OPC UA server from a third party software and create .s and .e files using OPC UA connector. However, I am not able to connect to the server and the utility shows me error. With UA Expert, I am able to connect to the same server. Please find the attached screenshots and some error messages.

Please let me know if you need further information or have further question. We can also organize a short google meet. Please let me know your availability in this case.

With best regards,
Nihar Shah
