I have a persistent message that tells me I have expired certificate. I fix it then the printer operates OK for a while then the error reappears. My fix last time was to go into the EWS and generate a new certificate and make sure the time and date were synced. This time I can't get it to work.

 

I've tried the solution someone else posted about using Keychain Access.app but there are no certificates there to delete.

 

I suspect my issue is to do with time and date. rather than a certificate because the certificate is already set to 2036. Selecting 'Sync' in EWS throws my date back to 1.00.00AM.
