I'm still having problem using this miner to connect to ethermine ... anyone knows what's wrong with my command line?

EthDcrMiner64.exe -epool us1.ethermine.org:4444 -esm 1 -ewal 0x362613b3bb5fb1e2bcd6b015674ed7a5877c90cb.rig1 -epsw x

I keep getting this message:

ETH: Stratum - Cannot connect to us1.ethermine.org:4444
ETH: Stratum - Failed to connect, retry in 20 sec...

Thank you.
