Hey, I thought I solved the issue with the outdated certificate by doing this,
And it worked! …At least for a day, and then I got the same error as before.
So now I need to update the certificate manually each day.
I already checked if the time settings are correct, and they are. So, I'm out of ideas.
Can anyone help?
FYI I'm on osX but I updated the certificate on a PC

Secure AirPrint may need to be enabled
I do not know how to enable it as I do not have a Mac and it is only mentioned in the above forum article. You will need to register with Apple and ask.
