Well have I got some good news for you !  After 4 months of having an SR open and many many techs attempting to figure this out, they found out what was happening.

When you export the ISO and it opens a new browser tab (that ends up throwing the error), notice the port it is connecting to is 9084

Change this to 9087 and reload the page and the ISO will start downloading.  I tested this in both my vCenters (7.02 and 7.03) and it works fine.

I have no idea why it works out of the box on 9084 if you don't use custom SSL certs, but after this long troubleshooting I'm ok with just changing the port and reloading the page.  Let me know if this worked for you as well.
