Open nginx.conf and modify:

client_max_body_size 500m;

After restarting nginx, the upload size exceeds 200M video will only report an error:

2. Modify the php configuration

Open php.ini and modify:

upload_max_filesize 500M
post_max_size 550M
memory_limit 600M

Restart php.

Note: Why upload_max_filesize

For a request to upload a file, the following equation exists:

POST DATA = File Base64 form other project data,

HTTP DATA = HTTP HEAD POST DATA.

The file size is limited by upload_max_filesize,

The size of POST DATA is limited by post_max_size,

The entire HTTP request data will be placed in the memory cache first, that is, the size of HTTP DATA is limited by memory_limit limit.
