Timeout-Disconnect to photon server

Options
Hello everyone!
I cannot seem to launch photon properly in my unity environment. Each time I try to launch a photon demo, it never connects I think and sends back error messages such as :
- Timeout-disconnect! Command: CMD(2 ch#/sq#/usq#: 255/1/0 r#/st/tt:8/7520/10114) now: 14611 challenge: 62d3c7ff
- Resending: CMD(2 ch#/sq#/usq#: 255/1/0 r#/st/tt:7/3998/10114). times out after: 3520 sent: 3998 now: 7520 rtt/var: 200/5 last recv: 9629

It seems to be having a problem starting from :
IPhotonSocket.Connect() ns.exitgames.com:5058 this.Protocol: Udp

Can some one tell me where the problem might be coming from?
