I have an ASP.NET Webforms application with a web API on .NET Framework 4.6.1 hosted in Azure. I am trying to validate an access token using JwtSecurityTokenHandler for external access to the web API and am getting the following error:
IDX10501: Signature validation failed. Unable to match key:
kid: '
{count} votes

2023-03-02T15:56:39.5533333+00:00 So it turns out there is an issue with the jwt access token. When I decode the token using the tool at https://jwt.io/and attempt to look up the public key using the kid, I do not find an entry with the specified kid. I have also notice that the kid value has not changed since yesterday which I would have expected.
