webhook 401 – The REST API has been restricted to authenticated users.

{
"code": "rest_api_authentication_required",
"message": "The REST API has been restricted to authenticated users.",
"data": {
"status": 401
}
}

I keep getting the error above. I have whitelisted Stripe IP’s to Cloudflare, Wordfence & WP Armour.

I’ve deleted and recreated the webhook 3 times.

But I still get this error – any ideas what else I can do?
