problem with connecting to a hidden service

[Sambuddho Chakravarty <sc2516@xxxxxxxxxxxx>]

Hello All
I have a web server which I run as hidden service. The configuration 
file is the default configuration supplied with the Tor source code with 
appropriate changes to specify the hidden service directory and service 
IP etc. I observe only intermittent successful connections to the 
service. I to monitor the log messages of the Tor client. This is what I 
see on unsuccessful connection attempts

Jul 11 04:37:56.513 [notice] Tried for 120 seconds to get a connection 
to [scrubbed]:80. Giving up. (waiting for rendezvous desc)
Jul 11 04:44:02.957 [notice] Tried for 120 seconds to get a connection 
to [scrubbed]:80. Giving up. (waiting for rendezvous desc)



The web client (wget) used to  connect to the server fails with 503 
Forwarding Failure.


What could possibly be the problem ?


Thanks
