I'm not sure what is happening, but I have the following setup:

• 2 Servers - An App Server and an Nginx Proxy Server
• App Server has 2 distinct wordpress apps running on httpd.
• Proxy server redirects traffic to both apps.

For the app server, lets call the apps 'app1' and 'site2' to distinguish the applications.

• App1 runs on 443
• Site2 runs on 7443

I have an nginx proxy config (under the conf.d directory) located here - https://pastebin.com/VAQ1fFrV - and each site is split up for easy reading.

What I cant understand is this:

Whenever I try to go to the nginx proxy address for site 2 (site2.serverhostname.com) it always, without fail, redirects me to app1.serverhostname.com.

I've never run into this before setting up similar proxies and sites. So I'm unsure why this is now happening. I am at a loss as to why nginx is behaving in this way.

If it helps, in my pastebin I've included the nginx config and the apache httpd config. Hope to hear soon.
