Login Error in Visual administartor

Hi Experts,

I am getting error while try to login into Visual Administrator like below login with <SID_ADM>.

For that, I have release the 8106 port in firewall, and restarted the system, but no luck.

System Details:

Netweaver portal 7.0 ehp 2 (JAVA Stack).

Can any one please help me out to resolved the issue.

Thanks in advance,

Regards,
