Ok, I got it to work by adding "used-by cli" and then entering again for "used-by web".
radius server host <SERVER1-IP> key <KEY> used-by cli
radius server host <SERVER1-IP> key <KEY> used-by web
radius server host <SERVER2-IP> key <KEY> used-by cli
radius server host <SERVER2-IP> key <KEY> used-by web
radius enable
