I am trying to connect to the standard project server using Remote UI from a client PC. I keep getting a certificate issue and can't connect to the server. How should I set the certificate when configuring the Remote UI Project? I can connect fine using the desktop UI.

What is the difference between Remote UI project and the Dekstop UI in your project configuration?
If you want to get assistance you must provide more detailed information which kind of certificate error you get. Possibly you can get in contact with your common WinCC OA support to get assistance.

By default the DesktopUI downloads the certificate files from the server. With a remote UI the (certificate) files are not automatically downloaded/put in the project.
Copying the certficate files to the UI project should resolve the issue.
