When using System.Net.WebClient, the Progress version, Progress certificate cache and the use of Certutil are irrelevant. In my experience, if you can get to the site using IE, you should be able to get to it using WebClient. The same may be true when using Chrome but I'm less certain of this. While using IE, it might be worth adjusting the TLS options under Internet Options/Advanced to see what's actually required for the site. If you can connect with only TLS1.2 enabled, then the same should be true in the WebClient. If not, you may need to enable more than one TLS version as shown in the code I sent. When testing with IE, be sure to clear the cache between tests. I'm not at all sure what, if any, impact the proxy might have on all this.
