Unable to Register the server to Landscape(Cloud Based) Portal

[mahesh]

Hi All,

We have installed landscape client on one of the ubuntu 14.04 server and trying to configure the landscape client but getting the below error.

Error Message:

The server's SSL information is incorrect, or fails signature verification!
If the server is using a self-signed certificate, please ensure you supply it with the --ssl-public-key parameter.

Client machine is full internet access and i can able to access "https://landscape.canonical.com/".

We are trying to register with the Cloud based Landscape. I'm able to register other client servers with the same step.

Help to register the server with landscape portal.
