TV streaming stops working?

I have the KDL-55w805c as a TV and now nothing can be streamed, say no YouTube, Twitch etc. Some time ago it was still on iPad and mobile, so I think that it is a problem from the TV. I've already tried updating the Cast app, but a connection error is reported, which does not exist because I can watch Netflix and Amazon. Need help and thanks for the answers in advance.

Were mobile and iPad in the WLAn, when it went with it?

Otherwise it almost sounds like proxy settings. Who has access to the router?

Reboot - hold down the power button for several seconds until the TV reboots. If the problem persists, check if the TV is connected to the internet and if your mobile is also in the WLAN.

Can it be that he has blocked certain pages?
