I am trying to upload 30MB file on my server and its not working.
When I upload 30MB file, the page loads \"Page Not Found\"
Assuming that you made the necessary changes in your php.ini files:
You can resolve the issue by adding the following line in your nginx.conf file found in the following path:
/etc/nginx/nginx.conf
then edit the file using vim text editor as follows:
vi /etc/nginx/nginx.conf
and add client_max_body_size with a large enough value, for example:
client_max_body_size 20MB;
After that make sure you save using :xi or :wq
And then restart your nginx.
That's it.
Worked for me, hope this helps.
