If an attempt of key pinning backfires, it won’t go as planned. The error itself means that the keys you have tried to pin isn’t bound to the pinned certificate. Also, these keys are not interchangeable, and failing to pin the right key to the right certificate can break the website.
To put it another way, you just don’t have to pin only your own keys, you also have to pin the keys for the whole certificate chain means saving the root, and whose key is included in the root stores. And the reason is that, whenever the visitor arrives at your website, the server on which your website is hosted presents the certificate of the user’s browser. So, the browser uses those public keys for verifying the signature on every certificate and traces it back to the certificate, which has left it.
Nevertheless, there’s always the possibility of mis-pinning other intermediate public keys while pinning your own certificate, and it can create a problem.
The simple fix to avoid such a problem is: STOP KEY PINNING.
Experts also advise the same that it’s best to avoid key pinning. Lastly, it’s best to re-install your SSL/TLS certificate and if there are any intermediates in the standard manner. Ultimately, it can also mean that you may have to remove the configuration made previously, which takes around a few minutes.
