FortiVpn

Hi all

any one has any ideas ! desperate for help 

forti ssl vpn stopped working , when I'm connected to office internal WiFi , it connect's but doesn't give me internet access 

when I'm attempting to connect outside of the internal WiFi it give me an "unable to reach host" error

I've no Idea what to do.

Policies seems to work fine nothing has been changed but somehow the vpn managed to stop working.
