502 Bad Gateway on Windows 2003 Server

[Martin Boehm]

Hi all,

May I kindly ask for your assistance on this issue.

We have the following problem with one of our webservices. Since our
customer uses an automatic proxy configuration script, we have to use a
proxy server for making our webservice requests. This works fine.

Recently we've got another webserver (works with Windows2003) and hosted a
new instance of our webservice there. When connecting to the new webservice
we always receive the following errormessage:

*********Error Information*********
Error Message: The request failed with HTTP status 502: Bad Gateway.
Error Type: System.Net.WebException
detailled error information:
System.Net.WebException: The request failed with HTTP status 502: Bad

The funny thing is that calling the webservice functions from a browser
window on another machine works fine. It seems that there must be some
configuration setting that must be set.

Has anyone else encountered this problem already?

Any help is appreciated!!!

Hello Durgaprasad,

first of all thanks for your reply. I have to ask for permission to do the
netmon sniff, and will provide them to you as soon as I have them.

In the meantime, here's some more information:

Calling the webservice from a browser window works fine (both locally and
from another client). We also have another asp.net web application running
on that machine, too. Sharepoint services is also running on the machine.

Accessing other webservice instances using the same proxy on our other
server works fine. Our original server is called opus.intra.customer.com
whereas we access the new system by using the servername, e.g.
http://newserver/webservice_421/service.asmx. All sites from
intra.customer.com are within the local intranet zone.

I will contact you again, when I get the netmon sniffs.

Thanks in advance & Best Regards

Martin,
Could you send me the NETMON Sniffs?

Hello Chris,

Thank you very much for your reply.

We also have another .Net webapplication (no webservice) running on the same
machine, which connects to the same ORACLE database which works fine.

Additionally we are also able to retrieve data from our webservice by using
a browser window, so I think the connectivity libraries should be installed.

Best Regards
Martin dot Boehm at opus hyphen gmbh dot net

You also will get this if you are accessing Sql Server (or probably any
other DB) and the connectivity libraries to that DB are not installed.

So if you are accessing Sql Server make sure the run time connectivity
libraries are installed on your server.
One of our client had that problem and this solved it.

Chris.
