I´ve inspected some of my logfiles.
In the error.log of my hosters apache there are the following entries:
[Tue Oct 13 15:02:06 2020] [notice] [Cloudflare] ERROR: [CLIENT API] Array\n(\n [type] => request\n [path] => https://api.cloudflare.com/client/v4/zones?action=cloudflare_proxy\n [timeout] => 30\n [method] => GET\n [headers] => Array\n (\n [Content-Type] => application/json\n [Authorization] => Bearer HERE IS MY API TOKEN!\n )\n\n)\n
[Tue Oct 13 15:02:06 2020] [notice] [Cloudflare] ERROR: [CLIENT API] Array\n(\n [type] => response\n [reason] => Forbidden\n [code] => 403\n)\n
[Tue Oct 13 15:02:06 2020] [notice] [Cloudflare] ERROR: Forbidden
Did this help for anything?
