antpool eth not working

[nerdralph]

I noticed antpool supposedly supports eth:
https://www.antpool.com/support.htm
I already had an antpool account from mining BTC, so I tried mining eth.  stratum-eth.antpool.com:8008 is live and accepts TCP connections, but won't establish a stratum connection when I try it with sgminer.
MPH and other pools I've tried work fine, so it shouldn't be a problem with sgminer.
Has anyone successfully mined eth with Antpool?
