Have a Pro-HD slingbox that I'm able to view fine when not on my work corporate network, but get the following message when trying to view the output on the corporate network:
"We detected very poor Internet connectivity or a loss of Internet connection. Please verify that your Internet connectivity is working fine before retrying."
All other websites resolve OK, and the rest of the sling website reolves OK, just the embedded video player that fails with this error. This hapens on Chrome, Firefox and IE browsers on Windows 7 OS.
Can you advise which ports this player is using so I can enable them in the corporate firewall or proxy to resolve this issue?
