Thanks for the reply!
I don't know the reason, but I work-around this issue by add a new entry in the /etc/hosts with something like 'web2 {id_address_of_web2}' and it can work.
I am not sure if that is due to some mis-config by my end of the deployment script, will further investigate.
Thanks all for the help!
