iirc. If something disappears from the accessories page it means it's currently out of stock. It might be showing as a 'problem' because of that. The page is hidden from the public/inactive and you're using the direct link so is throwing up the error but hopefully when it comes back in the page should start working again.
I had a similar problem on Friday, upgrading to an Oppo N2 Flip, it was showing in stock but as I went to confirm the order it said something went wrong and didn't work. Called customer services who advised in between me setting up and trying to confirm the order that the last one in the warehouse had become unavailable. When I tried to look at the Flip page after I hung up it was doing exactly the same as above error message
You can call 150 and speak to someone in Sales to see if it is available or if not when it might come back into stock? Alternatively, a pain I know, you could call around your local stores and see if they have any in stock. I was fortunate when I called mine store, they had one left, in the colour I wanted, which they were happy to sell to me.
Good luck!
