When I try to connect to a shared volume on another Mac on my LAN, I get "Connection Failed."
If I try to connect with "Go > Connect to Server..." and use IP address, it works fine.
But if I try to mount through Finder window "Go > Network" I get "Connection Failed."
Both machines are on El Capitan, both are logged in to the same icloud account, both have the same user/password.
I can see the icon for the other machine, but when I double click I get "Connection Failed."
Clicking "Connect As..." just changes this to "Not connected."
