Looking at the XWin.0.log you attached, it looks like the X server is starting
up successfully.

If clients are unable to connect, this might be due to firewall configuration
or other software which interferes with cygwin sockets (see [1] in the
Cygwin/X FAQ for some suggestions)

This seems slightly different to that failures you were seeing before, where
the Request packet did not arrive at the destination (although the reason for
that was never clear)

Can you send me the corresponding .pcap file, please.

This seemed to be working for you back in March (see [1]), so I guess the
important question is "what has changed?"
