SmartThings stopped working??

[userBiqYBtg3F3]

Anyone else have this issue? Just realized that it stopped working in my Alexa routines because SmartThings showing the tv as offline. My other 2 Samsung TVs are fine. So I deleted it, and no matter what it won’t re add. Keeps getting the attached error. No clue what to do now. I ruled out the possibility of if being my network by hooking my phone and the tv to a hotspot. Still nothing. I reset the smart hub multiple times. Signed out of account, signed back in with the smart hub reset. Nothing. Just keeps giving an error. Anyone know how to fix this? I tried it with my iPhone 17 pro max, but also tried with my Samsung galaxy tab as well. So even a Samsung android device won’t work!

image too big to upload but it says setup via phone failed. Set up manually. 
then in top right corner it’s a SmartThings logo and says registration cancelled. 

idk how to setup manually, is there a way?

Seems to be a global issue, there's a reddit post about it too.

Submit feedback via the Smartthings App > settings > contact us > Error etc.

Can't register the TV after it went offline.

Thanks! Samsung support helped. Flash reset fixed it. Problem now is that I can’t get Alexa to turn the tv on anymore, only off.

Sorry, what do you mean by flash reset as I am still having this problem?

Hold power on tv for 5 seconds. Let go. Then hold power on remote 5 seconds. Let go. Tv will fully factory reset and flash reset which is diff from normal factory reset. All settings are wiped. Worked for me

Im having this same issue. I have a Q80 from 2020. I really don't want to do a hard reset just yet. Ut I know I may get to that point. My TV went offline in Smart Things. Diagnostics detected error. I removed the device and tried to re-add it. I get a pop up on the TV that says "registration canceled " hoping the reset works out for me. Just want to add my comment here that I too am having the same issues.

Yep...did the hard reset and it worked! My TV was able to connect to Smart Things.
