Can't connect Amazon Redshift database to QlikSense Error

I am trying to connect a Redshift DB to QlikSense but I am getting the following error:

ERROR[08S01][Qlik]Amazon Redshift Error occured while trying to connect:[SQLState 08S01] could not connect to server: Connection timed out (0x0000274C/10060) Is the server running on host "XXXX" (XX.XXX.XXX.XXX) and accepting TCP/IP connections on port 5439?

All of the credentials are correct as I can connect via Aginity fine.
