Can't connect with Windows Client, but i can reach the Xibo admin page

Hello everyone,

i’m trying to connect a Windows Client to a Xibo local server. It keeps reporting error “impossible to connect to the remote server”, but if i click on “Display Admin” on the Xibo Player i can see the Xibo login page. I shut down the firewall on both computer but it continue to report the same error…

Anyone can help me?
