Not sure if this will help, but since you have Windows 7 have you tried patching the TLS to ver 1.2? (link here)
I know that Win7 is stuck on TLS 1.1 by default. To get it to correctly update to 1.2 you have to run the patch, and then the easy fix, both.
Not sure if that will fix your problem, but it can’t hurt to try.
