This may be more widespread than you think. It has happened to me frequently during the past year. I have power cycled the PVR with no improvement. Annoying issue.
Oooops-expired cerificate problem is back again today. Problem started Monday afternoon, then was fixed by Eednesday afternoon, and now back again. Come on Telus
It's not fixed. I am still receiving expired certificate popup warning. I'm using eM Client for email. I tried your turn off/on 10 seconds suggestion. Help?
