Could not connect to Rational Team Concert, Check if the ser

I am running Rational Asset Manager setup. The applications were successfully deployed, DBs working and connecting properly. User and authentication successfully completed.

Having issue during the : Configure Lifecycle management settings

I provide the URL - https://sapreal.bcsdc.lexington.bm.com:9444/jazz , Enter the correct userid and password and click on 'Configure Server' and get the following error -

Could not connect to Rational Team Concert, Check if the server is running

I also tried using the url -https://sapreal.bcsdc.lexington.bm.com:9443/jazz

but get the same error.

Is there any resolution?

Thanks,
