windows 10

I have tried to load kodi on my windows 10 system.
while the kodi app loads fine , when i try to load any addons i keep getting the error msg unable to connect to the server, not connected to the server, ect ect.
not sure what im not doing right or what im doing wrong. watched many viedos on how to , what to, but still the same results, nothing will load. any help on this matter will be greatly appreciated.
