JES4 Gateway issues

I'm having a gateway,rewriter proxy for my portal server 6.3. All the copmonenst are JES4 version. When I try to access the portal desktop, I get the following error:

Unable to connect to host - Session: Unable to connect to host: xyz.abc.com

The message in /var/opt/SUNWps/debug/srapGateway.empl is:

Response

HTTP/1.0 502 Bad Gateway

Date: Thu, 05 Oct 2006 19:22:04 CDT

Pragma: no-cache

Server: sun.net

Allow: GET

Content-Length: 193

Content-Type: text/html;charset=ISO-8859-1

Connection: close

If I restart the gateway and rewriter proxy, I get the login screen for the first time only. Upon subsequent requests the same error message repeats. All the certificates are valid. If anybody happened to come across this problem, pleease let me know how it can be resolved. Is it something to do with the portal patches? Appreciate your response.

Thanks in advance,

We got it working. It was due to a security patch 119213-09. We backed it out and rebooted the box that resolved the issue.
