Iphone doesn't apply changes in the hosts file

I decided do jailbreak Iphone 6s ios 15.2 For my device, only the semi-tethered jailbreak from palera1n was suitable. After palera1n icon appeared, I decided change: /private/etc/hosts file using filza using Webdav. For convenience, I changed the file: master.passwd and set the password for the root user. The changes worked. Now I can connect both via WinSCP and via Putty. My problem that no matter what sites I put in the hosts file, they are not applied, that is, both Safari and Firefox continue to open them, ignoring the hosts file. Here is the hosts file: 127.0.0.1 localhost 127.0.0.1 localhost.localdomain 255.255.255.255 broadcasthost ::1 localhost 127.0.0.1 local ::1 ip6-localhost ip6-loopback 127.0.0.1 www.youtube.com ::1 www.youtube.com 127.0.0.1 m.youtube.com ::1 m.youtube.com 127.0.0.1 dzen.ru ::1 dzen.ru Judging by this hosts file, Youtube and Zen shouldn't open, but they continue work. What could be the problem? Thanks in advance for your reply.
