This one was a bit odd and the timing with my 13.1 upgrades didn’t help.

Certificates can be such a pain. Glad you got it sorted Nathan. And, welcome back to the Community! 🙌🏻

Thanks Shane.   Was a real weird one and the timing with the veeam upgrades was a nice touch :-)

Hope to get back to a little blogging now.

It for sure was! 

Great to hear. When you do create those blogs, make sure to share them here so we can benefit! 😊

Great post ​@Nathan Oldfield at this time of transition, as certificate validity periods shift from 12 months to 6 months – and then to even fewer months in the future – it is important to be familiar with these procedures in order to resolve any issues that arise when certificates are renewed.

Thanks for sharing !

Seems we might have jumped the gun with the diagnostics yesterday.  Blog has been updated, Veeam case updated and awaiting feedback.  And still hunting down a few things.  I’d be keen to know if anyone else has seen similar behaviour.

Hi ​@Nathan Oldfield we use an “expansive cert” and for now I don’t see any similar issue.

  • After upgrading a tenant deployment to 13.1, Backup Copy jobs targeting a Cloud Connect repository fail when the service provider uses a publicly trusted SSL certificate and the certificate revocation cache is empty.
