.NET OIDC redirect in Kubernetes

We have a .NET 5 (Blazor Server) app running in Azure Kubernetes that uses OpenID Connect to authenticate with a 3rd party. The app is running behind Ingress. Ingress uses https. The app is only http. After we authenticate with OIDC and get redirected back to /signin-oidc, we get a .NET error that we haven't been able to solve.
