Wallet not syncing and not connected to Internet on my PC

Hello,

I was just trying to setup a masternode for the first time. So I began to download your wallet for Windows, but after successful install, I can see that it is like not connected to Internet. My firewall is allowing it, and the same for antivirus, Xuez wallet is added into the exceptions so it should properly work.

Any idea of the problem? Thanks in advance!

Best Regards
