I’m waiting on Prosys to receive an evaluation version of their SDK so I can troubleshoot this. ---

The latest version of the Prosys SDK is able to connect to my development Ignition UA server without issues, but I do see the error messages you’re getting when connecting to a 7.5.1 release Ignition UA server. This means that my current UA interop work has fixed the issue, so the next Ignition beta or release version will contain the fixes necessary to get rid of the errors. ---

Ignition 7.5.2 beta 3 is currently available. In 2-3 weeks the stable release should be available on the website. ---

I had uncommitted changes when beta3 was published, it may not be fixed in that version. Should be in beta4 or the final though.
