Problem publishing visualizer to cognos connection

[sasha73]

Hi

I am not being able to publish Viz reports to the Cognos connection
I had published the viz in upfront and made sure i cleared the checkbox on the viz server properties that enables only upfront as the portal so that 3rd portals can be used..

also i included the following in the system.xml

<!-- Series 7 Integration parameters-->
- <param name="series7">
<enabled>true</enabled>
- <!-- character encoding used by series7-->
<encoding>series7_character_encoding</encoding>

- <!-- host and port to connect to PPES-->
<host>server_name</host>
<port>8010</port>
- <!-- PPES gateway location-->
<gateway>/cognos/cgi-bin/ppdscgi.exe</gateway>

- <!-- host and port to connect to VIZ-->
<host>server_name</host>
<port>8060</port>
- <!-- VIZ gateway location-->
<gateway>/cognos/cgi-bin/vizcgi.exe</gateway>

- <!-- host and port to connect to UPFRONT-->
<host>server_name</host>
<port>8030</port>
- <!-- Upfront gateway location-->
<gateway>/cognos/cgi-bin/upfcgi.cgi</gateway>

- <!-- Prefix for ReportNet back URLs when linking to series 7 content-->
- <!-- (eg.

http://ReportNetMachine)-->

<back-prefix>

http://server_name/crn</back-prefix>

</param>


Can anyone tell me what is the problem
Thanks
