SNMP Notification - WCF Connection not available

I am trying to set up SNMP notifications in SANHQ, but when I click SNMP notification settings, I get a popup that says WCF Connection not Available. There was a post from 2017 marked solved called Dell EqualLogic San Headquarters - SNMP Notification Settings, but there wasn't really a solution in there that helped me. Can anyone lend some help as to how to enable these WCF settings? I've gone to Control Panel>Programs>Turn Windows features on or off>.Net Framework 4.8> WCF Service, rebooted and nothing. Thanks.
