Cannot connect OpManager to SQL DB Server

Cannot connect OpManager to SQL DB Server

I'm attempting to install OpManager 11.6 Enterprise as a primary server in our environment. When I reach the point in the installation where I need to connect to the SQL server, I am putting in what I believe is the correct information but getting an error that the host name or port number is incorrect. I've tried using the SQL SA account as well as my account with domain admin privileges. I've tried the FQDN for the Host Name as well. The port 1433 is open for TCP on the SQL server. Is there something I'm missing?
