Question about p2pools..

I've never successfully been able to connect to any p2pool listed on the p2pool site.  Yes, I connect to verters and coinotron with ease, but not p2pool.

I constantly get "no connection errors".  Yes, I've used my wallet and pass x for miner, but no luck.  I would rather bring my mining "power" over to the p2pool in order to help balance the coin.

Suggestions?
