I created a redshift in aws console. the I went to cluster created and based on the information I got in the console I used them in SQL Workbench/J. To set up sql workbench/JI used the following:

https://docs.aws.amazon.com/redshift/latest/mgmt/connecting-using-workbench.html

So here is my setup:

Now when I try to connect to it I get the following:

Any idea how I can fix it or what is going on?

UPDATE

Answer 1

Did you choose "Publicly accessible" YES (radio button) when creating your cluster? If that is set to NO then you can only access the cluster from inside your VPC.

You easily change this in the console by navigating to the cluster, clicking the Cluster ˅ button, clicking Modify . Then change the "Publicly accessible" selection and click the blue Modify button.
