ADMU3011E when deploying Cognos in Connections 4.5

I had a cognos for connections 4.5 to deploy, and I keep getting error. cognos_server was unable to start with WAS error into cognos-configure.log

ADMU0116I: Tool information is being logged in file
           /opt/IBM/WebSphere/AppServer/profiles/CognosProfile/logs/cognos_server/startServer.log
ADMU0128I: Starting tool with the CognosProfile profile
ADMU3100I: Reading configuration for server: cognos_server
ADMU3200I: Server launched. Waiting for initialization status.
ADMU3011E: Server launched but failed initialization. Server logs,
           startServer.log, and other log files under
           /opt/IBM/WebSphere/AppServer/profiles/CognosProfile/logs/cognos_server
           should contain failure information.
Waiting for Cognos services started.

I noticed that i left populated this variable also on linux

# The following property is only required for Windows systems.
# The fully qualified host name of this Application Server
# Example: host.example.com
was.fqdn.hostname=cognosnode.test.com

I changed the property to was.fqdn.hostname=

Then I cleansed everything

on linux this mean /opt/IBM/WebSphere/AppServer/profiles/CognosProfile/bin/removeNode.sh, ( if federated) then
/opt/IBM/CognosTR/bin/uninst -u -s
/opt/IBM/CognosBI/bin/uninst -u -s

then, after stopping all running servers

./manageprofiles.sh -delete -profileName CognosProfile

Then I cleaned the /tmp/folder  and the CognosProfile. Then I ran ./cognos-setup.sh, started cognos_server manually, ran ./cognos-configure and it worked correctly
