Autodock - Autogrid3 Authentication

Hello everyone.  I am sorry if this question has been answered before,
 but the archive search is currently down.
 Can anyone inform me as to how I can fix an Authentication issue using
 autogrid3 (part of autodock, which I am using through autodock tools).
 The authenticity of host '' (' can't be established.
 RSA key fingerprint is 3f:eb:79:0a:61:31:82:69:46:53:ed:06:51:f8:3b:74.
 Are you sure you want to continue connecting (yes/no)? yes
 Host key verification failed.
 I did have a successful calculation, but it asked me for my password 3
 times before it was complete.  Is this normal?  It is certainly
 annoying, and I want to see if I can avoid it.
 I tried changing the host script to use localhost (, but that
 didn't work either, I got the same authentication error.
 Any help in this matter is greatly appreciated.
