Im using asp net webforms and azure single sign on.

So, this has been working in the past, and i have other web applications in the same server that uses the single sign on and works fine.

For one off my application, it stopped work for a while and gives me this error:

Access to XMLHttpRequest at ‘https://login.microsoftonline.com/cd99fef8-1cd3-4a2a-9bdf-15531181d65e/oauth2/v2.0/authorize?client_id=c9b2c8f3-add2-4259-af86-f3cd19ad3113&redirect_uri=http%3A%2F%2Flocalhost%3A49262%2FDashboard&response_type=code%20id_token&scope=openid%20profile&state=OpenIdConnect.AuthenticationProperties%3D(…)’ (redirected from ‘x’) from origin ‘x’ has been blocked by CORS policy: Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

For what i can read, this is a problem from microsoft side and not from mine. Can someone assist me please?
