Fix 502 & Speed Issues

Job ID: 40597139

Budget: ₹600 – ₹1,500 INR

My site has begun throwing 502 “Bad Gateway” errors and pages now load painfully slowly. The first signs appeared only recently, right after I made a few server-side tweaks, so I’m confident the root cause lives somewhere in those configuration changes.

I need a developer or sysadmin who can:

• Inspect the current server setup, trace the exact trigger for the 502 responses, and eliminate it without breaking existing functionality.
• Optimise overall performance once the gateway problem is solved so page-load times return to normal (or better).
• Explain what went wrong and document any adjustments so I can avoid a repeat in future.

The site runs on a standard LAMP stack, so experience with Apache/Nginx, PHP, MySQL and common caching layers (e.g., Varnish, Redis, opcode caching) will help you move quickly. If you prefer other diagnostic tools—New Relic, GTmetrix, top/htop, log analyzers—feel free to bring them into the workflow.

I’m ready to give you SSH/hosting-panel access as soon as we agree on the approach and establish a quick rollback plan. Let me know how soon you can start and roughly how long you expect the investigation and fixes to take.
