Cardano rosetta node sync issue


I’ve started the Cardano rosetta node using docker as per the instructions provided here

But from logs and I’m getting below errors.

[dbaabb7d:cardano.node.DnsSubscription:Error:60] [2021-04-22 07:37:45.78 UTC] Domain: “” Connection Attempt Exception, destination exception: Network.Socket.connect: <socket: 26>: timeout (Connection timed out)
[dbaabb7d:cardano.node.ErrorPolicy:Notice:50] [2021-04-22 07:37:45.78 UTC] IP ErrorPolicySuspendConsumer (Just (ConnectionExceptionTrace Network.Socket.connect: <socket: 27>: timeout (Connection timed out))) 20s

Does anyone know the reason?

and this will run local cardano node as well, right?
