postman 关闭ssl,该请求已中止：无法创建SSL / TLS安全通道，但可以在浏览器/ POSTMAN中使用...

I am kind of at a lost here. Adding the ServicePointManager stuff usually fixes this but this time I keep getting the error below. My server can access the same URL from the browser and POSTMAN. But running this through the website fails. This works on my local computer though. I have TLS 1.1 and TLS 1.2 enabled on the server.

I am using CertifyTheWeb certificates, basically free SSL. Not sure if this has anything to do with it.

I am sending to the link below which is rejecting the request when made from the code below from IIS.

It was a configuration issue on the other server in Apache. They loosened their SSL configuration, which I am not sure what they did but their previous configuration is below. I can now make a HTTP request to their server.
