Do not load the Wordpress plugins from the computer. How to solve the problem?

Hello! Is there a website on Wordpress, the server Ajenti V. Everything is working except one function - do not load plugins from the computer. If you download plugins from the plugin directory (Wordpress is in the console itself), then everything works, so the problem is obviously with the fix to the server.
When I load the plugin, it downloaded about 60%, then everything is reset and the browser says "web page unavailable". Tried to change in php.ini values for upload_max_filesize, max_execution_time, max_input_time, but to no avail.
How can this be solved?

for snafu traffic, error code server issues of some sort?

The webserver what? nginx, apache, something exotic?
if nginx client_max_body_size try to config nginx paste.

Problem 146% not php and the webserver. In order for an accurate diagnosis to install.. look at the logs.
