Receiving error : No valid key mapping found for securityToken - frequently

    Question

  • Hello,

    We have deployed one MVC application to cloud service and authenticating using Azure AD.

    We have uploaded the certificate and correct thumbprints. But we frequently get below error message and everything stops running. Then we change the new thumbprints on the certificate and it starts working.

    WIF10201: No valid key mapping found for securityToken: 'System.IdentityModel.Tokens.X509SecurityToken' and issuer: 'https://sts.windows.net/7bf1e99c-af3d-4152-9486-3dc1e156677a/'.

    Can anyone please explain what should be the root cause of getting thumbprints changed on Azure? How to resolve this permanently?

    Thank you
