Can i ask if you're on an old wallet?
As the most recent wallets have the nodes built in, so you dont need to add them manually.
I'm on the latest wallet, and i connect within a few seconds.
If you do have to update the wallet please read the instructions carefully

Im on "version" : "v1.1.0.0",
I used the master branch to compile from source yesterday.
So do you have any working nodes you can share?
