.Net 4.7.2 mvc web app configured with okta oidc authentication.
The app suddenly started throwing and IDX20807 error after being perfectly fine for 1.5 years.
The error states that it is unable to retrieve a document from “https://{oktadomain}/oauth2/default/.well-known/openid-configuration” my AuthorizationServerId was set to ‘default’ in my web.config .
However after this issue started occurring, i set my AuthorizationServerId to null and it is working. i’m wondering if anyone can help me figure out why this is working now, and what must have changed (i’m assuming in the okta org configuration) for the AuthorizationServerId to have to be set to null for my app to start working again.
Does AuthorizationServerId = null make the above url: “https://{oktadomain}/.well-known/openid-configuration” ?
