Cannot add/search for new series

SOLVED, Solution at bottom of post

When I go the the Series tab, and try to add any series (Let’s say Chuck for Example), nothing seems to be working.

I see the message :" [GET] Service Unavailable : /api/series/lookup?term=chuck " in the bottom right on the window.

System Log Page shows:" TvDbProxy- The operation has timed out: The operation has timed out"

Can someone please help me determine what the problem is.

SOLVED!! With the help of some members of the community it was pointed out that something was wrong with my Internet Explorer Settings. Everything else seemed normal, but I could not access thetvdb.com through Internet Explorer. This is what I did to solve the problem.
Open Command Prompt as Administrator.
Then do both of the following commands:
netsh winsock reset
netsh int ipv4 reset

Reboot.
