I'm encountering the following error when trying to connect to WCF API which is behind a HTTPS Proxy :
The server certificate with name 'CN=hostname' failed identity verification because its thumbprint ('X') does not match the one specified in the endpoint identity ('Y'). As a result, the current HTTPS request has failed. Please update the endpoint identity used on the client or the certificate used by the server.
Where X is the thumbprint of the certificate used by the proxy and Y the thumbprint of the certificate used by the service
The problem is that I managed to get a token from the STS but I cannot perform any web service call after that.
I reproduced the problem on my PC by using a local SSL proxy, the certificate used on the proxy is trusted on my PC. Everything is ok when using HTTP.
I searched a solution for several days now and I noticed this KB article which is close to my problem but not applicable anymore (I'm running the sample and the server in .Net 4.5) : https://support.microsoft.com/en-us/kb/2564823
What am i missing ?
