i have problem connecting comodo trust connect :(

i have a problem in connecting to free comodo trust connect account it says -
cannot resolve host address - us2.vpn.comodo.com [no_data] the reuqested name is valid but doesnt not have an ip address
–mute triggered–

i use proxy in lan to connect to main sever to surf internet in college
i installed comodo firewall and antivirus also
and antivirus was giving me same problem before in updating then i put the proxy address in settings now it updates fine

is any way for comodo trust connect to work or will it not just work on lan? help

You may specify TrustConnect work via a proxy.
Please, refer to: TrustConnect Windows Client Configuration Guide for details.
