socks5 proxy work for some website , but not for some

[oldunclez]

There are two hosts

1. socks5-server(3proxy server) (192.168.1.100)
2. client-host (192.168.1.200)

I can curl any websites on socks5-server,
but if I curl websites on client-host via socks5-server ,
some websites work ,for example , www.baidu.com , www.qq.com .
some websites not work : www.google.com , www.youtube.com .

Any hints for debug why fail to curl google and youtube ?
Thank you

it means somewhere between Client and Server there is something that blocks it.

[oldunclez]

It turns out that the client-host is dns-hijacking .
so I have to use curl -vk -x socks5h://192.168.1.100:1080 https://www.youtube.com/ on it .

31.13.94.36 belongs to facebook rather than google,
% host 31.13.94.36
36.94.13.31.in-addr.arpa domain name pointer edge-z-m-mini-shv-01-eze1.facebook.com.

174.37.175.229 belongs to Softlayer, rather than google. You definitely have DNS issues.
