If Not Healthy
Click Access Gateways > Edit > Service Provider
Certificates and replace any missing or expired
keys.
Verify that all members of the cluster have
sufficient bandwidth to handle requests. If a
cluster member is going down, the problem
resolves itself as other members of the cluster are
informed that the member is down.
If a cluster member is slow because it doesn't
have enough physical resources (speed or
memory) to handle the load, upgrade the
hardware.
Restart the Access Gateway.
Modify the Identity Server configuration and add
an Identity Server.
Configure the Access Gateway to trust an Identity
Server configuration. See Section 1.1.1, "Creating
a Proxy Service," on page
Check the network connection between the
Identity Server and the auditing server.
