Skype not working!

[Imanol]

I've had this issue many times, what I do is I change my port in the Connection settings.

Watch out if you're getting a DDoS attack, try blocking your skype IP from strangers in Options-Advanced-Connections.

I get that happen to me all the time, because of my pretty dodgy internet. Maybe that's something you should look at, although if you're able to connect to other services (Eg. this website, Minecraft servers, etc) then I'm baffled as to what the problem is.

Are you using proxy on skype?
