FP4, Android 13, no videos in browser on news page (ntv.de)

Hello, since a few weeks I cannot start videos on a news page (www.ntv.de). It doesn’t work with ecosia, chrome, and firefox browser. Videos on other websides and also youtube work.
I already deleted the browser cache, checked add-blocking and Java-script.
Any idea?
Thanks in advance!
PS: English or German is fine for me.

Maybe you have an adblocker, PiHole etc?

Thanks! I wanted to say no, because I did not install an add-blocker.
But: I used a “Privat DNS” dns.adguard.com.

That was the reason. Now it works.
When I used Opera with VPN Yesterday, it also works - ignors the DNS setting I forgot.
