Redshift -- Connection refused, whitelist issue

Looker Q&A Looker
1

Getting the error: Connection refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.

I am self hosted, running on aws/using redshift.

I’ve tried white listing everything I can think of.

what specifically do I have to white list to not get this error? I’ve tried the IP of the website that is hosting looker

thanks

The IP of the machine hosting Looker should be sufficient, I would triple check that and ensure the proper ports are open, not just IP addresses. Make sure it’s the public IP, not the private one.
