Herelink - Cannot register your device

Hi, I can’t register my herelink.
I asked the product key to my seller and I put the right time (GMT+1 Madrid). I’m living in France so I put EU for the region.
I read some posts about ip adresse so here is my configuration:

IP address
fe80::218:7ff:fe19:f283
2a01:cb18:80ba:100:218:7ff:fe19:f283
2a01:cb18:80ba:100:4084:651b:ab1f:500f
192.168.1.82
Wi-Fi MAC address
00:18:07:19:2:83
Serial number
8e7345f1

Could you help me to solve this ?

Can you try again with connecting to different networks?
Eg: hotspot from your phone/public wifi
