I've tried much of the advice I've found on here and it hasn't worked so far.
Here's my network flow:
HTTPS -> Cloudflare -> NGINX (server 1) -> Apache (server 2) -> WordPress
Here's my system tools:
Server 1 - NGINX, BitDefender (firewall), not sure if it matters but I have Flask running, and ive ensure my SSL certs from let's encrypt update automatically and are current.
Server 2 - BitDefender (firewall), XAMPP running Apache (serving port 80) and mySQL, PHP 8.5, WordPress 6.9 (with a few plug-ins, all updated - including Dokan Pro 4.2.1)
Most of my site runs without issue. Occassionally, I will get a 502, but not often. The Dokan vendor dashboard summary is where the consistent errors are happening.
On server 2, I've configured my nginx.conf to play nice with cloudflare, included the cloudflare IP ranges in the http { } block, set cloudflare SSL to Full (Strict), and proxy_pass to http://server-1-IP:80.
On server 1, I've commented out "Include httpd-ssl.conf" in Apache, letting Cloudflare serve my SSL. In my php.ini, I've disabled opcache and opcache.jit.
My theory is that PHP 8.5 is causing issues with some of my plug-ins (even though Dokan 4.2.1 says it is compatible) and I need to drop to PHP 8.2 for more stability. But before I do that, I want to see if there isn'tsomething else, I should look into first.
What are some things i can look into to resolve the issue??
PHP isnt throwing any errors, but Apache is throwing repeated errors in quick succession:
