Trying to mine with NBMiner on MiningPoolHub I get a connection timeout - if I manually run the miner changing the URL from "ethproxy+tcp://us-east.ethash-hub.miningpoolhub.com:17020" to "nicehash+tcp://us-east.ethash-hub.miningpoolhub.com:17020" it works fine.

I'm not sure how or if there's any way to change the URL for a pool, but I would really appreciate it if someone could help.
