Re-writing this topic since the issue is worse than I believe first. Oneboxing doesn’t work anymore on my forum unicyclist.com and I don’t know why. See: https://unicyclist.com/t/oneboxes-not-working-anymore/272954/5?u=canapin I got 404 errors like GET https://unicyclist.com/onebox?url=https%3A%2…

Oneboxes ya no funcionan

It’s working again. I have no clue why.

"Onebox Assistant", crawl for those previews reliably!
