Hostinger "managed" WordPress. Site throwing 502s. Their support: "we manage the server, not your application." Transparent about scope at least, but I misunderstood the line.
What I've ruled out:
- MySQL connection limit (40% of max)
- PHP-FPM pool exhaustion (pm.max_children not hit)
- Disk full (68% usage)
502 comes from Hostinger's nginx upstream, not my origin. But they won't check their own gateway timeout against my backend. "Application issue."
I need community eyes. What am I missing? Error budget for this host is burning fast.
