Hi Team,

I have installed Cognos Analytics 12.0.4 all components on two separate machines/servers. I have a single DB2 machine as content database.
1. cognosprod01 - primary
2. cognosprod02 - secondary

I have updated the two content manager URIs in the environment configuration.
1. https://cognosprod01:9300/p2pd/servlet
2. https://cognosprod02:9300/p2pd/servlet

I have updated the dispatcher URIs for gateways also as below.
1. https://cognosprod01:9300/bi/v1/disp
2. https://cognosprod02:9300/bi/v1/disp

When I'm starting the cognos services on both servers. Only prod01 is getting started properly. prod02 server get stuck at CM-REQ-2378 A request was received to start the negotiation process to determine which content manager instance should become active.

as of now each server has its own entry in Gateway URI field.

Content DB server is reachable from both server.

Cognos services start successfully on the server where I start them first, the second one goes into this error.

Do I need to configure HTTP server before I start the services on both cognos server and update the Gateway URI. So that cognos services comes up properly on each server?

OR

Do I need to exchange keys between these servers, so that they can communicate with each other. I'm using TLS1.2, HTTPS and Third Party Certificate Authority.

Or this error is because of something else?

Kindly guide me, if I need to so some other configuration.

Will follow this link to configure HTTP server (https://www.ibm.com/docs/en/cognos-analytics/12.0.x?topic=server-configuring-http-v9)

Issue is resolved after I exchanged the Certificate of servers with each other. Thank You.
