'Could not reach CMS' error

Hi Everyone,

I am using the SAP BusinessObjects Enterprise XI 4.0 Edge edition on a virtual machine with Windows server 2012.

I am able to call RESTful services from a remote system but while trying to use the Java SDK, I am getting the following error:

Could not reach CMS. Specify the correct host and port and check for network issues. (FWM 20030)

I am getting this error while logon:

enterpriseSession = sessionMgr.logon(username, password,  cmsConnection, auth);

• cmsConnection is in the format "hostname:port"
• auth is 'secEnterprise'

I have made sure that the ports 6400-6410 are open on the Virtual machine. I also tried to restart the servers. But nothing helped.I am unable to find a solution from existing forums. Can someone please help me out?
