What is the curl error 52 “empty reply from server”?

Question

I have a cron job setup on one server to run a backup script in PHP that is hosted on another server.

The command I\'ve been using is

curl -sS http://w         


        

Answer 1

Curl gives this error when there is no reply from a server, since it is an error for HTTP not to respond anything to a request.

I suspect the problem you have is that there is some piece of network infrastructure, like a firewall or a proxy, between you and the host in question. Getting this to work, therefore, will require you to discuss the issue with the people responsible for that hardware.
