License Key could not be installed , Invalid user or password

Hello,

My HANA studio working fine before 2 days. But after installing one CISCO VPN client software on my PC ,I am not able to connect to our HANA box.

Sometime it gives License Key could not be installed(though we have valid license) and sometime Invalid user or password (though my collegues are able to login into system with same user id details from their machine).

I have already reinstalling the HANA studio but no luck. I am able to ping the HANA box as well.

Any hint will be much appreciable.

With Regards,

Rafikul Hussain
