I'm new to Magento and not a *nix pro, so I hope I'm just making a rookie mistake here. My setup...
Magento 2.1.4 CE CentOS 7-3.1611 nginx 1.12.0 (SSL termination only) Varnish 4.1.0 Apache 2.4.25 PHP 7.0.15 MySQL 5.7.17
Everything seems to work fine with http (non-SSL), but I need to use https for all pages.
When I enable https, everything seems to work fine except the CHECKOUT PAGE IS EMPTY (i.e., the "GET /checkout/" request returns "200 OK" but "Content-Length: 0"). There are no messages in the browser console. I'll mention that I'm using a self-signed certificate for development, but it seems to work okay.
If I go to the cart page (/checkout/cart/) first, I get errors in the browser console (which do NOT occur in non-SSL)...

There are a few more messages (which I can include if they'll be helpful), but the above seems to be the relevant section.
Can anyone help me? I'm going bananas with this.
