We are seeming to have problems with the MailChimp plugin developed by NopCommerce directly. The client has two MailChimp accounts and thus two API keys to enter into the app, but notably the NopCommerce site is using a Multi-Store configuration. When trying to save the information for one specific account (after selecting it from the Multi-Store dropdown), we are seeing the following error in the log:
Log level: Error
Short message: MailChimp error. The SSL connection could not be established, see inner exception.
Full message:
System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception.

Does anyone know anything about this? I have already reached out to MailChimp asking them the same thing since it has to do with SSL's and I assume it would be some issue with their SSL.

Checking it right now, the Windows version is Windows Server 2012 R2 Standard, Version 6.3.9600 Build 9600. The IIS version is 8.5. Other than that, the PowerShell command you provided wasn't recognized by the server. I had to go into the registry to find that info, but it looks like TLS 1.2 is enabled.
