I was tasked with experimenting with Duende Software’s Identity Server for a future project. Something strange is happening with the rendering of components which causes the app to lose all of the OIDC claims after logging in. I am having trouble tracking down the cause and possible fix.

In my Blazor webapp application I am trying to implement openIDConnect to connect to a remote Authentication API hosting identityServer4. When this API is up my application redirects to the authorities’ login page and returns and I can access pages with [Authorize] as expected.
