Could you paraphrase your question, please.
Do you get a list of servers on your screen?
-- if so: do all of these server show 0/0 for the players column?
-- if so: can you connect to a radomly selected server?
-- if so: try to search for a popular server, e.g. a HuH server (enter "huh" as a search keyword) or a Qi server
Did you check the "has players online" filter?
which OS do you run teeworlds on? (edit: Windows 7)
what happens if you disable your firewall temporarily?
