Since yesterday, the error has changed. When you press authorize, it does not even open the browser window. It simply displays, connection error.
From bad to worse.
THe worst is that Dlink support made me open a support ticket only to reply to me that the product is discontinued, but later they released a firmware fix that does not work.
Tragic.
Case solved!
Out of the bluw I decided to press authorize again, and the dlink webpage authorized me successfully. It is currently syncing.
100% right. They fixed the firmware, they forwarded to a special authorization page, and they took it down later. But they fixed it eventually.
In any case, lousy support, sorry to say,
