So that explains why Chrome and possibly Edge are unaffected by these issues. Chromium-based Edge might be the same/similar in this respect. Interesting fact - Chrome doesn't do OCSP checks by default (instead Google regularly pushes revocation lists to Chrome browsers). I have also noticed that affected URLs seem to trace to servers operated/managed by Akamai Technologies (they do a whole bunch of content delivery for Microsoft), so it could be an issue on their end. The issue seems to be affected by geography and the luck of load balancing, with only some users affected some of the time. Trying to install latest updates leads to Download error - 0x80070643 error. Instead I am forced to create a local account, which indicates that the installer is having trouble connecting to Microsoft's account servers. For example:ĭuring Windows 10 Home install on new PC connected to the internet, I should be asked to sign in to a Microsoft Account. The issues are actually not limited to Firefox.


Using Firefox, browsing to a number of Microsoft websites leads to a MOZILLA_PKIX_ERROR_OCSP_RESPONSE_FOR_CERT_MISSING error.
