cURL receives empty body response from Nginx server

I try to fetch HTTP content with cURL, but I only get an empty body in the reply:

[root@www ~]# curl -v http://www.existingdomain.com/
* About to connect() to www.existingdomain.com port 80 (#0)
*   Trying 95.211.256.257... connected

If I change the URL to another domain, like www.google.com, I get the content.

How can this be possible? And how to fetch content?

The server is free to send to the client whatever he likes, including nothing. While this is not exactly nice, there's little the client can do about this. You could

• check the server logs to see if there is some problem which makes him so calm (given the server is under your control) or
• try another client to see if the server does not like to talk to curl. You can then configure curl to mimic a regular web browser, if that helps
