SecuritySuite - SuiteCRM and CE Teams

Hi , My friend have installed SecuritySuite - SugarCRM CE Teams module successfully.He have installed this on local system. But whenever he enters key and validates key, it shows only loading image again and again and nothing will show nor generating any log in sugercrm.log. Whatever I have checked which is given as follows. - There is no any java script error on server that I have checked on browser console. - Also Curl is enabled on server. If there is some problem then it should generate any log at least. What about the firewall setting????? For which IP address I have to check the firewall.??????? Please provide help as soon as possible. Thanks In advance Ishwar
