Custom page for WAF Block, get the 500

I set a page to display when the WAF is blocking a page (403).
But oddly, it’s not this page, but the 500 page, which is displayed.
However, the custom page are corrects (previews work, they are pure HTML page, etc.)

Example :
I get a 403 status code, but the displayed page is my 500 template, not my 403.

500 template : Homair Vacances - Erreur 500
403 template : Homair Vacances - Erreur 403

Thanks for your help

It sounds like you’ve set it up correctly. How did you test the WAF page?

Hi, to follow up the issue, and give some feedbacks :

I found something interesting !
The HTTP status returned by the blocked page is 403, BUT… the page used the one for 1000x errors, and indeed, the code is 1020 !
I didn’t know that a blocked page obtains a 1020 (Troubleshooting Cloudflare 1XXX errors – Cloudflare Help Center)

If I understand, the 1020 code has nothing to do with the HTTP status, it’s an error code, not an HTTP code, isn’t it ?

The block page returns an HTTP 403 status code, but the error that’s presented is a bit more specific to the Cloudflare service that issued the block. In your case it’s a 1020, which is generated from Firewall Rules as explained in the document you linked.
