OK. SO. For whatever dumb reason, a bunch of websites and apps (disney+ and spotify in particular) refuse to load, only showing me this message.  What am I supposed to do??? Google isn't much help and I can't afford to reset smart hub/my TV as a whole (it's a shared TV.) I already confirmed it isnt a wifi problem. (My TV model code is UN65RU8000fXZC, meaning it's fairly new and not an outdated model.)

If it helps, here's the exact error I get for Disney+:

This Web page is not available.

Unable to load the page. https://cd-dmgz.bamgrid.com/bbd/samsung_tv_tizen/A/index.html may be temporarily down or have moved to a new Web address. 

Spotify and a bunch of other websites show me errors like this one, only with the link differing.
