Radarr settings for qB

[Zooi]

I'm trying to get Radarr to work with qB, but I cannot get it to work.
Can anybody tell me please what the right settings must be for "localhost" (I guess this is correct) and port number?
In qB I use a not standard number for "Port used for incoming connections".
Maybe I need a login and password, although I have not set a password in qB?

I use a router to connect to the internet

What is your router model? dd-wrt ? netgear?
