Issues with x509 certificate and identityserver v2

Question

I know that identity server v2 is deprecated but I'm trying to fix a production issue. We installed a new certificate on the servers and I updated the thumbprint in the web.config file but I'm getting the following error. I'm looked in the sdf file and didn't find anything there. I also tried to get tracing to work but I can't seem to generate log files (I was hoping it could tell me what the break down was) Any ideas?

<system.identityModel>
<identityConfiguration>
          <audienceUris>
            <add value="https://website.com" />
          </audienceUris>
          <certificateValidation certificateValidationMode="None" />
          <issuerNameRegistry type="System.IdentityModel.Tokens.ValidatingIssuerNameRegistry, System.IdentityModel.Tokens.ValidatingIssuerNameRegistry">
            <authority name="http://identityserver.v2.thinktecture.com/samples">
              <keys>
                <add thumbprint="thecertificatethumbprint" />
              </keys>
              <validIssuers>
                <add name="http://identityserver.v2.thinktecture.com/samples" />
              </validIssuers>
            </authority>
          </issuerNameRegistry>
        </identityConfiguration>
      </system.identityModel>
      <system.identityModel.services>

Answer 1

I had this issue recently when migrating to a new server. For me at least, it was related to the application pool's identity not having access to read the certificate's private key. This can be managed through the certificates mmc view.
