Are you using the most recent wallet?
http://syncfund.com/wallets.htmlEven if you are, we recently fixed the 'Add Nodes' feature which wasn't working for some and uploaded fixed version yesterday.
So go ahead and close your current and install and run the one linked above.
Yes is the most recent one.
I also tried to add node manually, it says that it has no connection.
As I stated other pos wallet (BC, Mintcoin) works. So I don't really know what the problem is...
Could you give me the tcp/udp port that I need to open?
