Unexpected kat.cr on Apple devices

Should I be worried that my new MacBook Pro and my iPhone keep having kat.cr request (when I'm not even on they website)

  • I do not even torrent or go on this website on this device, I might have a kickass tracker on my Synology/Jackett but definitely not on my Mac. (assuming that Kat.cr is kickass torrent)

Since this is a Pi-Hole forum, it would be difficult for us to give you advice on whether this should worry you. It does seem that Pi-Hole is working as intended and blocking this domain found in your gravity list.

ok sorry for the post
