Error help: Tunnel to dirserver failed

[Rochester TOR Admin]

Can someone help with the error below?  Whenever I enable a hidden service
on my server, I get this message:

Sep 10 18:04:18.540 [warn] Requested exit point
'$719BE45DE224B607C53707D0E2143E2D423E74CF' is not known. Closing.
Sep 10 18:04:18.541 [warn] Making tunnel to dirserver failed.

I was having this error and _then_ I upgraded to Tor version 0.2.1.5-alpha
(r16710) but it still occurs.  When I comment out the hidden service lines
(shown below) everything seems to to run fine.

HiddenServiceDir /var/lib/tor/hidden_service/
HiddenServicePort 80 127.0.0.1:9877

I've tried the following:
- manually updating the router cache from tor.xenobite.eu
- adding the lines TunnelDirConns 1 and PreferTunneledDirConns 1 as per a
previous discussion on this list

This is a first attempt to setup a hidden service and I'm basing my
configuration on https://www.torproject.org/docs/tor-hidden-service.html.en

Any help is appreciated
