nginx test failed after 11.5 upgrade

[TravisG]

After upgrading to 11.5, I get the following message in my control panel:

New configuration files for the Apache web server were not created due to the errors in configuration templates: nginx: [emerg] "proxy_cache" zone "otto-cache" is unknown in /etc/nginx/nginx.conf:40 nginx: configuration file /etc/nginx/nginx.conf test failed . The error message containing the detailed error descriptions was sent to you by e-mail. Please resolve the issues and click here to generate broken configuration files once again or here to generate all configuration files.

If I try

/usr/local/psa/admin/sbin/httpdmng --reconfigure-all

I get

Execution failed.
Command: httpdmng
Arguments: Array
(
    [0] => --reconfigure-domains
    [1] => domains.com (all my domains),
)

Any ideas?

There is no 'proxy_cache' parameter in default nginx configuration:

# grep proxy_cache /etc/nginx/nginx.conf
# grep 'proxy_cache' /etc/nginx/conf.d/*

Check this parameter in included config files in /etc/nginx/conf.d/ directory. Looks like that you have some customization there.
