Frequently Asked Questions

What does an HTTP error status code mean?

HTTP status codes communicate request outcomes. 4xx codes mean the client did something wrong (404 not found, 403 forbidden, 429 too many requests). 5xx codes mean the server did something wrong (500 internal error, 502 bad gateway, 503 unavailable, 504 timeout). The exact code tells you where to look for the fix.

How do I fix HTTP 500 Internal Server Error?

500 means the server crashed processing your request. Three places to look: (1) Server logs (Apache error log, nginx error log, your Flask/Django console). (2) Database connection or query errors. (3) Unhandled exceptions in your application code. If you see 500 in production, check application logs first; the actual error message is usually clear.

How do I fix HTTP 502 Bad Gateway?

502 means the proxy (nginx/Apache) couldn’t reach your application server (gunicorn/uvicorn/PHP-FPM). Check: (1) Is your app server running? systemctl status gunicorn. (2) Is it listening on the port nginx expects? netstat -plnt. (3) Are there OOM crashes killing the worker? dmesg | grep -i oom. Restart the app service first as the quick fix.

What is the difference between HTTP 401 and 403?

401 Unauthorized: you’re not logged in (or your auth token is missing/expired). The fix: authenticate first. 403 Forbidden: you’re logged in but don’t have permission for this resource. The fix: check user roles/permissions. Two different fix paths despite similar-sounding names.
