hello there i have a problem with Unity, when i try to put my password and email pop up to me this msg “service not available , please try again later”
how i can fix that please ;
. sorry about my English 
Weird… I only saw that screen with the little bar at the top when I first started Unity.
Normally when I log in I see this:
(I use Ubuntu 14.04 LTS)
Another possible issue is that Yahoo is currently unavailable.
Verizon purchased Yahoo on the 25th… they may have shut some services down temporarily.
Do as it says. Try again later.

This problem often occurs in Windows 8, and 10.
Run cmd.exe as an admin and enter the following commands:
netsh winsock reset
netsh int ipv4 reset
netsh int ipv6 reset
After doing this it is better to reboot your system.
