Forgot to mention, using SSL on this site. Running nginx 1.8.1 (stable) The SSL is correctly configured and verified by third party testing tools.
Sounds like WordPress is blocked from making http calls for plugin info from ww.wp.xz.cn. Check your firewall.

makes sense, what port should I be opening?
Is this your own server? Are you the server admin?

Yes my server, and I’m the admin.
Try
$_SERVER['SERVER_PORT'] = 443;
in wp-config.php. This sets the server port to 443 for the whole site.
If that doesn’t work, you’re much better off at http://serverfault.com/ to learn how to configure a server and firewall for port 443 with an SSL and outgoing connections. There forums really aren’t for server admin.

I’ve done some more investigation on this, and I really don’t think its a server config issue. Here’s why:
– ran yet another check with another SSL testing tool and is configured 100% correctly (intermediate certs, etc).
– in SSH, ran a curl command to ww.wp.xz.cn and I receive back the entire page in the terminal, thus connection is OK.
– checked all iptables and they are correct – this is on a live server with other sites that are working normally AFAIK.
– I’ve reinstalled WordPress 4.4.2, cleaned and optimized the db tables (not much there to begin with).
– Made sure ALL plugins are disabled, and any cache files removed.
Here’s a BIG clue:
– When I go to the installed plugins page (none are activated), and choose any plugin and left mouse click “View Details”, a lightbox window appears which should show the details of that plugin (as read from the plugin file that’s installed within the plugins folder). However, the window is blank, there is only a blue “X” to close the window.
– However, when I RIGHT mouse click the same “View Details” link, but choose “Open in a New Tab [using Chrome], the tab opens up WITH THE CONTENT fully displayed. The URL is the SSL secured one for the site, as follows:
https://www.mysite.com/wp-admin/plugin-install.php?tab=plugin-information&plugin=adminimize&TB_iframe=true&width=600&height=550
So, in my estimation there’s something wrong with the lightbox?
Any thoughts on how to fix this?

In other words, the ThickBox modal lightbox used by WP is not being populated with content.
That’s not a typical WP bug. Try a different browser and check your security settings for Chrome. Check for javascript errors, too, in the dev tools console.

Found the problem.
I hired someone at upwork to look into this blank lightbox/modal window screen problem, turns out to be an SSL security setting in nginx to prevent clickjacking. I’m sure there’s a similar workaround for other server platforms.
Should be
# indicate that browser should be allowed to render a page within a frame or iframe.
add_header X-Frame-Options SAMEORIGIN; #I had it set to ALLOW BY URI or DENY
All seems to be working now.
Thanks for your help.
