I've the SAME EXACT problem.

from one day to another... it started to give this error.
it's a 3 server dns cluster (full servers), two of them get this error in between, the other two see the other with no problem.

ie. server A, B, C
A to B ok.
A to C problem
B to A ok.
B to C ok.
C to A problem
C to B ok.

any idea?

Additionally i got (on one side say server A to C)
HTTP/1.0 900 NET OR SSL ERROR /usr/local/cpanel/whostmgr/docroot/cgi/clusterstatus.cgi 10146: open_tcp_connection: failed

and like this guy (on the other side, say server C to A)
HTTP/1.1 401 Access Denied Still Working

ideas?
