Certificates not updating after most recent update

MMRHC

Noticed a renewed certificate hadn't updated in ITFlow. A manual refresh throws an error.

Cron has been updated.

This appears to be an issue with certificates on servers on the same local subnet. I had to change my DNS to 8.8.8.8 on the host instance to solve the email delivery issue caused by the introduction of email validation.

Not sure if it's possible to specify a specific DNS server for a particular cron script like certificate_refresher.php?

Obviously, I need email delivery more than I need certificate expiration notifications so it may remain broken for now.

Hello,

I would suggest this is more due to the way your internal DNS is setup. I've run into companies that run example.com as their internal AD and then can't access their own website internally. AD should use internal.example.com ideally.

The next update will let you run mail queue with --no-mx-validation so you can go back to using your internal DNS whilst still being able to send internal mail.
