Now. Notice the FD number (66) on the line at the top there. And look
for the very next set of headers with matching set of local=,remote=,FD
values but titled "HTTP Server RESPONSE".

That is apparently the reply that failed.

* Compare the timestamps of the request/reply lines to see if it reminds
you of any kind of timeout value you are aware of. Multiples of 30sec or
5min are common for timeout settings.

* anything visibly wrong about the reply headers?
