Connect time_out

[ccccccarrotyuan]

Dear HACC@NUS,

my name is Ziyuan Wang and i am of the clients from your platform.
Recently when I am trying to connect with SSH following the command with my username:
ssh ziyuanwang@xacchead.d2.comp.nus.edu.sg

I got an error like this:
kex_exchange_identification: read: Connection timed out

by checking the log (-vvv), the error infos are:
