It sounds like your app is successfully redirecting post-login - That’s good! I’m admittedly not familiar with Blazor but I imagine you have had a chance to look this blog post? Auth0 will just redirect the url defined in any sort of app config related to the specific SDK/technology. I see that you’re redirected to https://localhost/GrowkshPMSDashboard/callback in the HAR file, but I do not see a full authorize request wherein there would be a redirect_uri param.
