Hi All,

I'm currently having an issue opening a project on an Ignition Server. I am currently receiving an error that says:

HTTP ERROR 500 Server Error  
URI:/data/perspective/login/project\_new  
STATUS: 500  
MESSAGE: Server Error

There are actually two projects on this server, but only one of them receives this error. Both projects are inheriting the same parent project.

There was one error that I saw that may be a cause, but I'm not sure how to fix it:

Seems pretty clear that one project has invalid project authentication settings.

Just update the Identity Provider name under Project/General in Project Properties in the Designer  
That should fix it.
