Invisible Chunk Bug Solved

[Ruok2bu]

Im making a new issue for this in case the devs dont see the thread i commented on:

Background
With web panel block pointing to a website, for a player, the whole chunk was invisible. I have 2 computers in my network. One runs windows 10 (mine) and it renders everything fine with no problem. I have embeddium, oculus and brute force rendering culling installed and i can see the chunk fine. Another computer in my home network is running windows 11. On the other computer; whenever i go to a chunk that contains a screen, the whole chunk becomes invisible. I thought maybe it was embeddium, oculus and brute force rendering culling causing the issue on that computer so i removed those mods. It still renders that chunk invisible.

The only major difference hardware wise between the 2 computers is mine is an RTX 4070 while the other one is a GTX 1660 Ti.

Why its happening
After i typed this i started thinking more about what it could be and I FIGURED I OUT (i tested it both with embeddium, oculus and brute force rendering culling installed and uninstalled and it fixed it)! On that other computer i have pihole blocking websites (only whitelisted websites are allowed). Through more troubleshooting, when the client computer cant reach "mcef-download.cinemamod.com", it renders the chunk invisible. Why does that domain have to be reachable by client for chunks to load? It is for analytic purposes?
