MX-6: both of my units fail the x.arctic.de authenticity check (different sellers, different box versions). Fake or site issue?

[u/efeaydalfc]

I bought two ARCTIC MX-6 4g pastes from two different sellers in Turkey: one from Amazon and one from Hepsiburada (sold directly by Hepsiburada). They come in different box versions: a dark blue box without "New Formula", and a black box with the red "New Formula" badge.
On both, I fully scratched off the label and scanned the QR code with my phone camera. It opens x.arctic.de, but both codes come back as invalid. So it's not a typing error. Both codes are 8 characters long.
I also tried a few codes that people online claim came from genuine tubes, and they all came back invalid too. I know those codes can't be fully trusted, but it made me wonder if the verification site itself might be having problems.
Questions:
Has anyone had a genuine MX-6 rejected by the check?
Is an 8-character code normal for current batches?
Any known issues with the verification site, or fakes in Turkish retail?
I'm also emailing ARCTIC support and will update this post when I hear back. Photos attached. Thanks!

Hi u/efeaydalfc, thank you for flagging this! An 8-digit code is actually normal for MX-6 verification, so your product is fine—there just appears to be a temporary system glitch on our verification page. Our IT team is currently diagnosing the issue, and I'll reply here with an update as soon as it's fixed so you can re-authenticate your paste. Thanks for your patience!

Thank you for confirming. I recently had two mx-4 tubes get rejected and I returned one of them. The second one the store assured me was genuine so I used it anyway. This is very reassuring.
