Today I've found it really difficult to access my web-based hotmail email accout and also my One Drive. Annoying because I use them all the time. When I click on the link I get a screen with :
"An error occurred during a connection to onedrive.live.com. Invalid OCSP signing certificate in OCSP response. Error code: SEC_ERROR_OCSP_INVALID_SIGNING_CERT"
This has never happened before and other sites I access are fine.
Does anyone know why it is happening and what I can do about it ? I'm using Firefox.
