Webex access failed. Check the configuration and network settings.

I have 2 Cisco 8811 phones that have been migrated to Webex Calling from CUCM. They have been active and working with Webex Calling for several months. No changes have been made in Control Hub and users have been working normally. Now all of a sudden, when trying to trying to view recent calls or use the redial function, the screen populates the error "Webex Access Failed. Check the configuration and network settings." Calls can still be made and received with no problems. 1 of the affected phones shows offline and the other shows online. I have tried powercycles and factory resets to the phones to no avail.

Have you tried these phones on a different network - perhaps from your home where you likely don't have any blocked ports outbound? Your description sounds like perhaps your company firewall is blocking ports that weren't blocked before. Or perhaps Cisco has added ports to the required list you need to have opened. I'd give that a try.
