vSRX 15.1 on ESXi 6 Strange Console Issue

Dear members;

i have deployed a Juniper vSRX 15.1 (which runs as a virtuilized instance under Wind River Linux) as per standard documents:

http://www.juniper.net/techpubs/en_US/vsrx15.1x49/information-products/pathway-pages/security-vsrx-vmware-install-guide-pwp.pdf

But when i connect to the console over a network...i get a blank screen as shown in figure below:

As per esxi connection list:

[root@localhost:~] esxcli network ip connection list | grep 6666

tcp         0       0  192.168.0.253:6666               192.168.0.104:35994  ESTABLISHED     35715  newreno  vmx          

tcp         0       0  :::6666                          :::0                 LISTEN          35715  newreno  vmx          

the connection is established......

Please can anyone help with his strange behavior..otherwise other VM's are accessible over console without any issue...Moreover have a valid Enterprise Plus License....

PS: it is working correclty on KVM on Ubuntu

Waiting eagerly for your kind replies.
