Once again, SELinux bit me.. what a pain. It’s good, I’m sure for something. but dang, it’s always to blame.
Trying to set up an Apache reverse proxy. Kept getting a 503 error,

Did some googling, and thanks to Justin Ellison @ sysadminsjourney.com, he saved the day.
Simple command to allow the reverse proxy:
/usr/sbin/setsebool -P httpd_can_network_connect 1
