Unable to access the endpoint.

Hi Folks,

I have end point which requires .p12 certificate to access (which I already installed in the certificate keystore). The URL is working fine in the

browser and I can see the SOAP message generated   but when I try to access the URL from Visual Studio 2019  the following error appears. 

An error occurred while attempting to find services at 'https://api.xxxxxxxxxxx?wsdl'. The request was aborted:Could not create SSL/TLS secure channel.  

when I click on the details the following details appear:

Metadata contains a reference that cannot be resolved

Can anyone help me with this problem?

Regards;
