I have same issue serial 4021215805

I had a very similar issue and opened a ticket with Aeotec who responded with this

“Last year there was a change of security certificate, the old certificate expired at the beginning of March 2025. For devices that have not been activated by then and have a production date before March 2024 or have not received an update since March 2024, this means that activation is no longer possible. However, this only applies to devices that meet the following criteria: Device has purple packaging (EU Only) and Date of manufacture is before March 2024”

Mine was a UK version and they replaced it without any question. The new hub arrived and worked straight away.

I am having the same issue. Error 33-504. Serial: 3011332457

Any assistance you can provide would be appreciated.

38

@Itati
If I tell the hub to connect via wifi, I can see it attach to my network, and I get to a screen that says “Your Hub is being added to SmartThings”, after a while I get the message “Couldnt Register Hub” and error code: 33-505

39

@Itati
I tried over and over and over with wifi and it eventually registered.
However, now the device has a flashing orange light.
I can see it is on my network. It has an IP addr. No DNS issues. No blocked ports.
Any ideas?

Hi @sublimese
I see that you have successfully connected your hub.

For this specific case, I recommend that you contact Customer Support, as they can directly escalate the issue to the appropriate team and provide you with the best possible assistance.

From the ST app

  1. Open the SmartThings app
  2. Go to the menu tab at the bottom-right corner.
  3. On this page, select the option “contact us” and then go to “Error reports”
  4. Select the topic related to your issue and follow the steps to submit your support request

@Itati
I will do as you requested.
You need to update the instructions for the SmartThings Web page portion of your instructions. The link is to smartthings.com, but it redirects to Smart home with Samsung SmartThings | Samsung US. The samsung.com site doesnt have “email” as an option. When I click through the various options, I eventually get redirected to samsung support, who eventually tell me to go to: https://support.smartthings.com/hc/en-us (which also doesnt have email). The https://support.smartthings.com/hc/en-us page, when you click on “contact us”, simply takes you back to the samsung website, thus starting the entire process over again.

Thank you for your response! We will review and update it.
