Video upload limit. Reg.ru?

Question

PHP

Hi all!
I'm uploading video to the server through the site, I did everything, it works, but it doesn't load large files (~ 100mb) gives an error

Failed to load resource: the server responded with a status of 413 
(Request Entity Too Large)

Files up to 20mb are normally loaded.
Wrote to support last night! Haven't answered yet!
Googled! I found out that I need to change the client_max_body_size in the nginx.conf file, but I still don’t understand where it is located (My host is Reg.ru, Reg.Host-Unlim tariff).
In php.ini, all the parameters of the exhibition to the maximum

upload_max_filesize = 12000M
post_max_size = 24000M
realpath_cache_size = 12000M
max_file_uploads = 11
magic_quotes_gpc = Off
date.timezone = Europe/Moscow

display_errors= Off
log_errors= On
max_input_time = 24000
max_execution_time= 24000
memory_limit= 12000M

Tell me who knows how I can make the
PS download norms. My host is Reg.ru, tariff Reg.Host-Unlim

Answer 1

Shared hosting does not imply the possibility of editing software configs (at least in reg.ru for sure).
Ask the hosting support, they can prescribe.

Answer 2

Nothing will work without a dedicated server (vps).
