> Inductive Automation Are there any plans on fixing the annual certificate failures? Seams to me that if the server can generate a new certificate, it should have the authority to delete or add a new certification, if it notices the old one has expired. Other users like myself What does the 'brain trust' think?

You have to delete the offending certificate and restart. Ignition will make a new one, with another three-year validity period. Use the remote's UI to accept Ignition's new certificate.

Consider upgrading to take advantage of the option to create longer validity periods in the new UI.

{ v8.0.10 is ancient and buggy and hasn't been supported for a couple years now. This isn't the only reason to upgrade. }
