Can't Block a Website using Host File (Only Safari)?

I'm trying to block this website: www.blackhatworld.com using the host file. The lines I use are this one: 127.0.0.1 website.com www.website.com ::1 website.com www.website.com For some reason, this website keeps loading correctly in Safari. In Chrome and Firefox it does not load (as expected). I've tried to flush the DNS Cache & Restart the Mac, but no success so far. What could be the cause of the problem? I think it has to do with DNS record 65 (HTTPS) as stated in this thread: https://stackoverflow.com/questions/65972371/why-does-etc-hosts-not-work-anymore-for-some-websites-on-big-sur P.S. all other websites that I have in my host file are being blocked correctly
