We are using SharePoint Online with Provider Hosted app creates in ASP.NET. This portal gone live in December last year and was working fine till yesterday until we started facing the issues exactly after one year of portal going live. With this we have
realized this has something to do with the ClientSecret token expiration issue because we have been getting the "JWT token invalid" issue. Further to this we have started following the below article and was able to generate the new ClientSecret and
the same has been updated in Web.config file as well but still getting the same "JWT Token Invalid" error along with "Invalid Issuer or Signature" issue.

While above document suggest a method before ClientSecret being expired, but in our case we are trying to fight with the issue where our secret has been already expired. We have also waited for 12 hours after generating the fresh secret but nothing helps.
Has anyone else experienced such situation, could someone please help me with this ?
