I have an old EC2 instance with RedHat 6.5 installed. When I want to
yum check-update, it show following error:
$ yum check-update Loaded plugins: amazon-id, rhui-lb, security Could not contact CDS load balancer rhui2-cds01.ap-northeast-1.aws.ce.redhat.com, trying others. Could not contact any CDS load balancers: rhui2-cds01.ap-northeast-1.aws.ce.redhat.com, rhui2-cds02.ap-northeast-1.aws.ce.redhat.com.
I am able to connect other website, so I assume it is not due to network issue.
Does anyone has know how to solve this issue ?
