We adopted Public Key Pinning 1 year ago, not all web sites adopted it, the ones that did had issues, we've had issues in the past... WHY it happened this time is a mystery but I've since decided to decomission the use of Public Key Pins, for that we now advertise the headers with a max-age=0 expiry... You should now find the issue begins to correct itself.Eh, a simple question arises in the mind of an old former sysadmin - why, of all the peculiar sites I visit, is Xiaomi.eu the only one where this problem occurs?
Going forward on the next years SSL these issues wont be present.Firefox (61.0.1 on Windows) gave me a similar error (MOZZILLA_PKIX_ERROR_KEY_PINNING_FAILURE).
I solved by going opening the full History window (CTRL + SHIFT + H), right click on a xiaomi.eu entry and then clicked "Forget about this site"
