301 Redirect doesn't work


I am trying to track an event on my website with the FB Pixel on a button. However, the button is linked to an external URL (Deliveroo button). And on external URL’s, I cannot track an event. So my idea was to link the button to a page that doesn’t exist anymore and then redirect to the external URL. The url of the page that doesn’t exist anymore can then track that event and my visitor will be linked to the right URL anyway.

I added this redirect in the Hosting settings, but for some reason it doesn’t work.

What am I doing wrong or does someone have another suggestion?
