Some customers had this issue temporarily. Is this trouble that you're still having?
Yes, I don't think the issue is resolved; The community used a work around, but if you do a restore of the TV the issue will continue to persist until you do the work around again
Blocked cloudfront.net through Open DNS and verified through my computer that it is in fact blocked. Tried all methods mentioned and still not fixed. Interestingly, I changed my country code to British Virgin Islands and the Smart Hub test passes. When I switch back to USA the Smart Hub is stuck upgrading and the Smart Hub test fails on App test. Oh, and I have the Netflix affliction, too.
Frustrating to buy a $400 piece of electronics that does not do everything it is supposed to do.
SAMSUNG'S TECH DEPT. SUCKS!! Here's what we had to do. We have a UN55F9000 Smart TV. After a ton of calls to Samsung, and them remotely taking control and repeating all the same stupid steps, I gave up. I called a local repair place and they charged $99.99 to come out to fix it. It was worth it, wish I would have done it 2 weeks sooner. What he did was do a FACTORY RESET, different than just a reset that we can all do on the Hub. Samsung could have easily told me, or walked me thru this reset, but NEVER mentioned doing it. Like everyone else, I thought I had to block cloudfront and go thru all that, but my Motorola router doesn't allow blocking of URLs. This factory reset turns your TV back to when it came out of the box, so any adjustments you made from the menu will have to be done again, but that's no big deal.
So here's what the repairman did, and I asked him if he would show me what he did, in case I lose the hub again, and he was generous enough to do it again, so I could write down the steps. Its easy, but you have to follow these exact steps.
TV off - make sure red light is off too. Hit in succession MUTE, 1 8 2 , then POWER ON. (Big Red button on your TV remote, mine is top left). Then scroll down to OPTION - SVC - Hit select button - APPS RESET, Hit select button again, hit right arrow on remote - WAIT - Then MENU - SVC RESET, hit select button again, then if you did this all correctly, TV shuts off automatically. I can't remember if it turns on again automatically or not, but when you get the TV back on, and hit Smart Hub, it will be back, and you can then download your favorite apps back in, some may still be there. Check it to make sure you can get on the internet, such as YouTube.
If this helps even one very frustrated person, I will be happy.
He warned me to be careful and only hit on what he said, as its easy to screw things up if you hit the wrong stuff.
I tried that before I called Samsung. The Tech. I had walked me threw it again. They called back to Remote Connect and did it again. Still did not fix the problem. They put the Blame on someone else. Like check your Router make sure UPNP is turned on. And call XFINITY to help. I explained to them that i have 2 Smart Blu-ray players made by Samsung. Both are on the same network and they can download anything. It's not the Router it's not XFINITY. Silence.... Then I was asked is there anything else I can assist you with today? That's when I knew I was on my own.
