Hi both, just to add a “me too” to this.
I have 2 (free) projects, 1 works fine and behaves as expected, my new project (ASP .NET) behaves the same as Boris.
If I take the working DSN and place in in the “new” application, errors report without issue.
With the broken DSN I either get 403 forbidden, or { detail: “event submission rejected with_reason: ProjectId” }
Both applications coming from the same IP/platform
