IdentityServer MVC throws OpenIdConnectProtocolException when hosted in Azure

Question

I used the AspNetIdentity Quickstart as a basis.It works fine locally, but when I host my IdentityServer in Azure and use it with the local MVC application I get all sorts of errors:

Answer 1

I loaded my certificate from a local file, because I thought it was the least error prune solution until I got it up and running. Well guess who's wrong.

It worked locally, but gave above errors when I logged in on Azure. Funny thing is, it didn't fail on startup, there even was a public key exposed at

https://"MyIdentityServer".azurewebsites.net/.well-known/openid-configuration/jwks

Solution: Use a more sophisticated approach, see:
