Exact same problem here! - Aozi
If you're on Apache, edit your apache php.ini file (avoid editing the one inside /php/ since that's for the CLI context of php): find and replace this entries as follows: post_max_size=20M and upload_max_filesize=20M. replace 20M (20 megabytes) for any value you feel comfortable with. - Luis Masuelli

If you're running on nginx, this is the likely cause

In the nginx.conf

http {
    server {
        client_max_body_size 20M;
    }
}

Increase that to a more reasonable number and do some more testing.
