The issue I am facing:
I cannot perform a fetch request to my pihole instance because cors is blocking this.
Details about my system:
My pihole is behind a reverse proxy, where i already added the access-control-allow-origin header. I also followed the steps in this post: Cannot access api.php Json from localhost or different server.
I still get the message: "Failed CORS: mydomain.com vs 192.168.0.202, pihole.local.mydomain.com, pi.hole, localhost"
