ST m# IM6001-V3P01
I have factory reset the unit, and I have closed and reopened the app. Even restarted my phone. The router sees the Hub and it’s allowed access. Can ping it. It won’t register. I tried using cellular data instead and took off any wifi. Looking for last ditch help or it’s going back to the store.
what is the color of the led light on the hub? and you are using the SmartThings app and not the SmartThings Classic app?
Still flashing red and green
flashing red/green is a good sign…
try reading this support page to see if it helps…
but @Brad_ST will get you up and running 
Sorry to hear about the rough first introduction!
When you scan the code does the app return an error?
flashing, but it still says Couldn’t register hub no matter how many times I retry.
No error, let’s me continue the setup
@Flynn I think there may be an issue on our end. I will keep you posted but would recommend taking a break while we investigate.

There are no known workarounds at this time.
I’m not sure this is related, but I’m experiencing an outage of my SmartThings Wifi mesh network which is also serving as my SmartThings Hub.
Around the same time last night that Samsung reported an outage affecting their 2018 hubs, my mesh with 7 satellites went out. It’s flashing red. My wifi mesh serves as my SmartThings hub, so my entire house (with 220+ devices and 8 ActionTiles panels) is down and I have no wifi.
Any clues or recommendations are appreciated.
This issue was limited only to Hub v3 hardware.
Are you back online or still having issues with your ST Wifi?
back online
Went and bought a ST hub and an echo to go with my Yale Zwave deadbolt. Plugged the hub in and tried to download ST app on my Android 8 Samsung Galaxy J3 V (ST says it works on Android 6 and above). I get the message that it is incompatible with my device. I’m told either my ram needs to be 2G or better and the Bluetooth needs to be platform 4 or better. Way to go Samsung could have saved me a hassle of buying then returning if you had listed won’t work with other Samsung products. Every time I buy Samsung I regret it. I’ve had problems with a Refrigerator, a TV, Now a Phone and a Hub. I don’t think I’ll buy Samsung again
Hi there, I’m having issues with "“Couldn’t register hub” error. Are there any resources I can use to troubleshoot this error?
Hello! How did you fixed? I have the same issue now
I also have this issue. Error code 33-506.
I have reset the device multiple times now. It’s the Aeotec version.
