I attempted to play various media in apps and got a spinning wheel, black screen, and occasional error code (#3304 was a common one). I tried all the solutions listed in this thread and related threads -- manually setting DNS (to several different DNS servers), deleting and reinstalling apps, resetting the Smart Hub, and more -- to no avail. For me, the issue also extends beyond Paramount+, to Peacock, AppleTV+, and other services at times. It would seem to be a Samsung issue as much as (or more than) an issue of individual apps needing bug fixes (as Samsung claims). I solved the issue by deleting all apps from my Samsung TV and buying an Apple TV 4K. It works perfectly, has a much better interface, and is lightning fast. I heartily recommend it. ... View more

I'm glad the DNS reconfiguration trick worked for you. It did not, for me. I tried setting DNS manually to my ISP's default DNS IP address. I tried Google's 8.8.8.8 DNS service. I turned off IP6 service (since I don't have it turned on in my router). Nothing worked. Other threads suggest that Series 6 Samsung TVs are the ones primarily affected here, and I have one of those. Perhaps your fix works for other series? As it is, for me, until this week or so, I could stream anything via Paramount Plus without issues. Today -- despite resetting TV and app configurations many times -- Paramount Plus WILL only play the occasional content. Successful streaming doesn't seem to be connected to time of day, however. Something that wouldn't play time after time suddenly, unexpectedly, does. Presumably, this issue will be fixed with a Samsung Smart Hub upgrade or a Paramount Plus app upgrade. But neither company has claimed the problem or promised a fix. So ... maybe this will work better, sometime, in the future. I wouldn't count on it, though. On to other TV brands and other streaming services, I guess. ... View more
