Xfinity Home & Philips Hue - no longer working together?

Do the Philips Hue bridge and lights no longer work with Xfinity Home?  Recently, I've had issues with the Xfinity Home app indicating that my Philips Hue lights are "troubled" and are no longer synced with the Xfinity Home app.  I've tried resyncing the lights with the Xfinity Home app multiple times. In a fit of desperation, I removed the Philips Hue bridge and lights from Xfinity Home. I then tried adding the Philips Hue bridge and lights to Xfinity Home and keep getting this message, "We were unable to connect your account. Please exit the flow and try again later." I've also gone into the Philips Hue app to see if I can connect with Xfinity Home but it's not one of the smart home options.  The Philips Hue bridge is connected via a wired connection to the Xfinity gateway.  

I've had Xfinity Home for many years but at this point, I'm feeling really frustrated as I've had multiple issues with the system over the past few months.
