I have installed Report Server on testing server and have MWS running. After started Cognos c10 and tested out without any issue. But when I try to configure the report server and recieved the connection failure.

I opened SAG ticket and walk through the process but still unable to figure out why there is connection failure.

Refer to MWS wrapper log and have the following errors when configure the report server.

Is the localhost:8800 with port accessible? Did you check with you network team also?

May be try with DNS name or ip address which might give some light:

What options did you try to troubleshoot?

HTH,

Yes. MWS port no is 8800 and there is no issue connect to IS and OFI. They all running on the same server. I don’t believe it’s network issue. Also, I can check the cognos status from my laptop "[URL]http://sv62417:9300/p2pd/servlet[/URL]’ which means there is no issue for 9300 port.
