Hey there! We've found the following might help you get unblocked faster:

• 🧵 Increase max file upload with PHP Nixpacks

• 🧵 Laravel Image upload returns 413 (file too large)

• 📚 Deploy a Symfony App

If you find the answer from one of these, please let us know by solving the thread!

hi, to raise nginx’s upload limit on railway, you need to adjust the client_max_body_size in your custom nginx config and redeploy. you can do it like this:

server {

client_max_body_size 100m;

…

}

or include it under the http block to apply site-wide. then redeploy so nginx picks it up. if you’re using PHP, also bump upload_max_filesize and post_max_size in php.ini to at least the same limit. restart or redeploy after making those changes.

PHP file upload limits are still not being applied despite multiple configuration attempts, causing large file uploads to fail silently.

THE SOLUTION:

nixpacks.toml file:

[variables]

NIXPACKS_PHP_ROOT_DIR = '/app/public'

UPLOAD_MAX_FILESIZE = '150M'

POST_MAX_SIZE = '150M'

[phases.setup]

nixPkgs = ["postgresql", "gd", "libsodium", "php81", "php81Packages.composer", "nodejs", "nginx"]

cmds = ['UPLOAD_INI_PATH=$(find /nix/store/*-php-*/lib -name php.ini -print0 | tail -z -n 1 | rev | cut -c 9- | rev)/upload.ini; echo "upload_max_filesize=${UPLOAD_MAX_FILESIZE};" >> $UPLOAD_INI_PATH; echo "post_max_size=${POST_MAX_SIZE};" >> $UPLOAD_INI_PATH']

The most important thing is having the | tail -z -n 1 | as one of the commands inside the array of cmds as that specifies for nixpacks that it should look for the last config (the tail one) and not the first one (head)

this one you can modify a bit as I have but I'm pasting it because of the structure, the name of the file is really important. And I bolded out the important stuff:
