Normally the wallet gets an initial list of nodes from the seed nodes coded in. From there it requests the neighbor nodes, once it has a connection running.
You can try to add
46.4.0.101
Those are p2pool nodes, which have to run a wallet.
Also every pool should have a waller running and is a possible neighbor.
Additionally, how long did you wait for connections?
It may take 10 -20 minutes worst case to find additional nodes.
The debug.log file should give information, if your node gets a list of nodes and if it can connect to some of them
