Website player does not load

Hi,
I've been using NextDNS in Brazil for a while and everything was going well in terms of navigation.
I use this site "https://redecanais.wf/" to watch movies and series and it always worked fine, and out of nowhere the site player stopped working, it doesn't load anymore. I ended up thinking it was a problem with the site, and I left it that way for a while. But I ended up disabling NextDNS and the player loaded right away.
I disabled the lists and it didn't work either, so just using another DNS in place that works normally again. So it's something with NextDNS, before it worked fine even using NextDNS, something has changed and I don't know what it is.
