I am getting this error on the proxy SG version 1.1.3.1

Hi,
In version 1.1.3.1, the Proxy Admin Console is not the actual proxy.
I would guess that the proxy's SSL certificate either does not have an alternate subject name, or that the name (CN) of the certificate used by the proxy for management does not match the certificate.
 
For example, the certificate contains the FQDN and the short name in the alternate name, but you are connecting to the IP address of the proxy.
Or something like that. But this is just a guess on my part.

Best Regards,
Klaus
