I am using Windows 7 x64 on client 2.7b31.
I can log into the website (here) just fine, however when I try to log in via the ES client, it does not let me. Consistently says "talking"..."failed". When I go into the configuration file manually, the MD5 hash for my password is incorrect. Even after changing it to the correct hash (case-corrected) it still does not allow me to log in.
What am I doing wrong? Need more information?

it's not supported yet.
