The remote certificate is invalid according to the validation procedure. WCF Error

Question

we have recently change one of our .asmx service to .svc the issue we are facing is we are unable to call the service from : 1. an application hosted on the same server as the .svc 2. an application hosted on different server then .svc

it gives the following error:

1. Same server error: "The remote certificate is invalid according to the validation procedure. "

2. Different Server error: There was no endpoint listening at https://abc.svc that could accept the message. This is often caused by an incorrect address or SOAP action

We tried putting the certificate in the Trusted root folder and here is the error:

1. Same server error: "The remote certificate is invalid according to the validation procedure. "

2. Different Server error: An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail

   Here are config settings we have: Config details:

   Hosting Config

   Consumer config details [Different Server]

Answer 1

we figured our the issue to be one of the SSL certificate on the Hosting server:

We were calling the following website of the host:

https://example.com/qwerty.svc

the web-appPool example.com under IIS should have a SSL certificate binded to it, and the name of the certificate should be exactly same as example.com

In our case the name was a mismatch, which was causing the above error.
