I keep getting "The connection was reset" when trying to upload a large file (around 135MB). When I look at the "last_nginx.conf" of the website conf directory it says "client_max_body_size 128m;" I assume that is the upload limit, so how/where do I change it? It says not to bother changing the value in that file because it will only be overwritten. Btw Nginx is enabled via Plesk admin panel.
Answer to change vhosts nginx file is this :
mkdir /usr/local/psa/admin/conf/templates/custom/domain
cp /usr/local/psa/admin/conf/templates/default/domain/nginxDomainVirtualHost.php /usr/local/psa/admin/conf/templates/custom/domain/
add in /usr/local/psa/admin/conf/templates/custom/domain/nginxDomainVirtualHost.php:
<?php if (file_exists($VAR->domain->physicalHosting->vhostDir . '/conf/nginx.conf')): ?>
include <?php echo $VAR->domain->physicalHosting->vhostDir;?>/conf/nginx.conf;
<?php endif ?>
/usr/local/psa/admin/bin/httpdmng --reconfigure-all # to apply new configuration for all domains
As result, if domain has conf/nginx.conf - it will be included into virtual host config.
