Visual VM 1.3.4 error connection problem to admin

I have problems with VisualVM 1.3.4. It says cannot connect to admin. My connection is fine, and firewall is set too.
What could be the problem with this?

VisualVM 1.3.4
Error
Cannot connect to admin @192.165.254.162:100001 using service:jmx:mi///jndi/rmi:/192.165.254.162:100001/jmxrmi
Thanks,
Christopher
