Welcome code Hub STH-ETH-250

I have a Hub STH-ETH-250, but when I try to register it gives the following message:
The code has already been registered. Owner’s invitation is required to use this hub.
Can anyone help me?

Contact ST support and include an image of the bottom of the hub that shows the serial number.
