Unable to bind Beryl AX to GoodCloud after changing to AP mode

Hello! I am having an issue with binding Beryl AX to GoodCloud after changing it to run in AP mode. I also have Marble which I did change to AP mode as well but I did not encounter the same issue. The Beryl AX device has undergone probably about 3-4 factory reset over the past few months because I use it to test and play around with my homelab and made mistakes along the way. All the features of the device works well, but whenever I try to bind it in GoodCloud I am getting "Device Binding Failure". In GoodCloud, it shows in abnormal state with "router" in network mode.

When it is unavailable to connect to GoodCloud, is the Internet access of routers or clients available?

Please export the issue syslog and share it with me. Thanks.
