System.InvalidOperationException: IDX20803: Unable to obtain configuration from:

For some reason I get the following exception when I try to post something with my application.

My application is a .Net 5 React SPA

When I post something in my application, I get this error:

System.InvalidOperationException: IDX20803: Unable to obtain configuration from: 'https://dev-xxxx.auth0.com/.well-known/openid-configuration'.
 ---> System.IO.IOException: IDX20807: Unable to retrieve document from: 'https://dev-xxxxx.auth0.com/.well-known/openid-configuration'. HttpResponseMessage: 'StatusCode: 404

I’ll hope someone can help me to solve this problem.

Hey there!

Are you using any of our quickstarts / SDKs or are you making the post requests hitting our APIs directly?

I’m making the post request hitting the API.

So in that case to troubleshoot that we would definitely need more context and code snippets
