Can not Login with Root to VCAC Appliance HTTP Portal

Hello,

I just did an upgrade to 6.1 and I am not able to use my root password for the VCAC appliance.

https://vcac_appliance:5480/

I get the following error:

Login

Invalid server response. Please try again.

However, I am able to SSH and use root and password to login.

Any help would be appreciated.

Thank you!
