Unable to download credentials

Hello! I was following your guide to download the AWS MQTT certificate with no luck.

If I execute the following request (got with Insomnia, but curl returns the same):

* Preparing request to http://hub.api.surehub.io/api/credentials
* Current time is 2023-06-01T12:36:39.269Z
* Enable automatic URL encoding
* Using default HTTP version
* Enable SSL validation
* Enable cookie sending with jar of 2 cookies
* Too old connection (4506 seconds), disconnect it
* Connection 10 seems to be dead!
* Closing connection 10
* TLSv1.2 (OUT), TLS alert, close notify (256):

* Received 23 B chunk
* Connection #11 to host hub.api.surehub.io left intact

So the response body is:

v02:0::::1:::

Do you have any idea of what I'm doing wrong? Note that I also tried to reboot my hub to force a firmware update.

According to the the /api/me/start, here are the device informations:
