Another "Cannot Register Device" After Update Thread

I had been developing a custom build of QGC for a customer, but I wanted to revert the Herelink to factory to do some other testing. I had already done this process last week with no issues following the how-to. I repeated this process today, and this time I had to manually set the time zone which I didn’t have to do last week. Once connected to 5G wifi, IP outside of 192.168., product key matching the label on the back of the controller which worked last week, I can not successfully activate the unit.
I get no errors during the flash. Any ideas? SN is HX4060751900207.

please try again now, had a server issue

Thank you Michael! All good now, registered and updated as expected.
