"Getting a 413 status code - How do I fix 'Request Entity Too Large' errors?"
Hey everyone!
So I keep hitting this *413 status code* when trying to upload files to my server. Like, it just straight-up says "Request Entity Too Large." Annoying, right?
I’ve tried tweaking my nginx config with `client_max_body_size`, but no luck yet. Anyone else run into this?
What’s the best way to handle large payloads without the server freaking out? Are there other settings I’m missing?
Thanks in advance!
(Also, if you’ve got tips for Apache, drop those too—might help others!)
Hey! Had the same issue last week. For nginx, you gotta set `client_max_body_size` in both the http AND server blocks, not just one.
Also, don’t forget to restart nginx after (`sudo systemctl restart nginx`). If you’re still getting the 413 status code, check if there’s a proxy (like Cloudflare) capping uploads.
For Apache, look for `LimitRequestBody` in your config.
Hope that helps!
Ugh, 413 errors are the worst. If you’re using PHP, make sure `upload_max_filesize` and `post_max_size` in php.ini are also increased.
Sometimes the server rejects it before nginx even gets involved. Double-check those values and restart PHP-FPM if you’re using it.
Also, tools like Postman can help test larger payloads without wasting time on failed uploads.
For Apache folks:
Open your httpd.conf or .htaccess and add:
`LimitRequestBody 104857600` (or whatever max size you need).
But yeah, like others said, if you’re behind a CDN or load balancer, they might have their own limits. AWS ALB, for example, defaults to 1MB—yikes.
Debugging tip: Use curl with `-v` to see where exactly the 413 status code is coming from.
Random thought: Are you sure your nginx config is even loading? Check `nginx -T` to see the active config.
Sometimes the file is edited but not included in the main config. Also, if you’re using Docker, the config might be overwritten at runtime.
For large uploads, maybe split files or use chunked uploads? Libraries like Uppy or Resumable.js can help.
Yo, thanks everyone! Didn’t realize PHP settings could override nginx—that was totally it.
Increased `upload_max_filesize` and `post_max_size`, and boom, no more 413 status code.
Still weird that `client_max_body_size` didn’t throw an error though. Gonna test the curl tip next to see where it was failing. Appreciate the help!
If you’re on WordPress, this can happen with media uploads. The 413 status code might be from your hosting provider’s limits.
Some hosts (looking at you, shared hosting) hard-cap uploads at like 2MB. Check their docs or support.
Otherwise, plugins like “WP Increase Upload Limit” can override PHP settings, but YMMV.
Don’t forget about timeouts! Even if you fix the 413, slow uploads might timeout.
In nginx, bump `client_body_timeout` and `client_header_timeout`. For Apache, it’s `TimeOut`.
Also, Cloudflare? Their free plan has a 100MB upload limit. Just saying.
