Cannot access my hotmail account on Firefox - error code SEC_ERROR_OCSP_INVALID_SIGNING_CER comes up. Can access it on Internet Explorer. Not sure what to do!

Hi   !
Since last night this looks like an epidemic     - this is a misconfiguration on Microsoft's server side. If you want to, you can disable OCSP (which is a security mechanism) : 3-bar menu   (the three horizontal lines in the upper right corner, right under the closing X) => Advanced => Certificates panel And Let's keep our fingers crossed that Microsoft will fix the issue soon.


Another way to disable OCSP   (for now) : Type in the address bar   about:config   (press Enter) (promise to be careful, if asked) Type and look for the preference : security.ssl.enable_ocsp_stapling and set it's value to   false

It is best to reset this pref via the right-click context menu to   true  once you are done with this website.


Another user mentioned that 'No Proxy' fixed it for him :

Options => Advanced => Network tab => Connection Settings: 'No Proxy'.

Hi - thanks for the response. I disable OCSP and this worked for about an hour - then it went again. Tried all three options - none worked.

Maybe Microsoft is on the case.

Am I the only one with this issue?

Hi

No, it looks like many other people have been impact by this. Microsoft knows about this issue and is working on resolving it.
