Reverse proxy to node js throwing 503?

Question

Edit: See my answer. I found the solution, but I'll leave this up as reference.

I'm on CentOS 7 with Apache 2.4.6

I'm trying to have a subdomain of mine redirect to a node.js express web server. The node server is listening on port 8080 and I can use wget http://localhost:8080 to download the page I want to load, so to me that means the problem I'm having is with the Apache proxy.

I tried following this which led to this, and then also tried the suggestions here, but I'm still getting a 503 "Service unavailable" page when I visit the URL.

This is my virtual host for that subdomain (actual url changed):

<VirtualHost *:80>
  ServerName foo.example.com

  ProxyPreserveHost On
  ProxyRequests Off

  <Proxy *>
    Order deny,allow
    Allow from all
  </Proxy>

  ProxyPass / http://localhost:8080/
  ProxyPassReverse / http://localhost:8080/

</VirtualHost>

I worried mod_proxy and mod_proxy_http weren't enabled even though httpd -M showed proxy_module (shared) and proxy_http_module (shared) in the list, so I've added the following lines to httpd.conf:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

If there is anything obvious I'm doing wrong, or if there's any more information that would be helpful, please let me know! Thanks!

Make sure your nodejs server is running with correct port – Popeye Dec 28 '19 at 09:53 — Popeye, Dec 28 '19 at 09:53

Reading into the comments on one of the linked threads got my answer. I used the comment this caused an error "Service Unavailable" on my httpd until I did /usr/sbin/setsebool -P httpd_can_network_connect 1 from vladkras.
