[Cppcms-users] problem running hello.fcgi example

[<ni...@in...>]

I have followed the instructions for building and configuring the hello.fcgi example. 
 
hello.fcgi builds without error, and cppcms_run starts the application and 
webserver processes OK. 
 
But when I go to access /hello.fcgi with a browser, nginx returns a 502 Bad 
Gateway error. 
 
What am I doing wrong?
