We are using PHP ripcord client to call Odoo's XMLRPC server, but it appears to be failing. It seems it is timing out at around 190 seconds, but as far as I can tell, our nginx and odoo timeouts are >  300 seconds. Is there a socket timeout we need to configure specific to Odoo's XMLRPC server? (Odoo 10.0)

The timeout in odoo.conf:

limit_request = 8192
limit_time_cpu = 3000
limit_time_real = 3000

The error: 

file_get_contents(http://example.com:8069/xmlrpc/2/object): failed to open stream: HTTP request failed
