By default, NGINX supports max file upload size of 1 Mb. If users upload bigger files, they will get a “413: Request Entity Too Large” error. Here’s how to increase file upload size in NGINX to fix this issue.

Let’s say you want to increase file size upload limit only for HTTPS requests but not HTTP requests. In that case, the line client_max_body_size 50M to server block that listens to HTTPS port 443 but not the server block that listens to port 80.
server{
listen 80;
...
}
server{
listen 443;
...
}
You can also use the above approach, if you want to increase file upload size only for a specific website/domain/subdomain/app.
Let’s say you want to increase upload file size limit for a particular directive/URL. In that case, you can add the line client_max_body_size 100M. Let’s say you want to increase file upload size for /uploads folder
location /uploads {
...
client_max_body_size 50M;
}
