Rajesh Battala commented on CLOUDSTACK-6990:
--------------------------------------------
from logs
management server is not able to generate ssl key and trying to use the
fail-safe key.
console proxy is trying to initiate the connection and mgmt server is throwing
the request.
can you try disable zone, delete console proxy and re-enable zone.
Check why mgmt server is not generating the ssl key that would also cause the
issue.
