A small note (though it may be unrelated), some ip address ranges are not accessible from Vodafone TR (3G/4G) connections.

216.239.36.219 <- For example this address returns "HTTP 504" from Vodafone. There are some other addresses like this which happen to be around, randomly.

So it may be a misconfiguration on Vodafone TR Network, routers or such thing. Sample curl output below.

  $ time curl -vki 216.239.36.219
