Starting a couple of days ago, my Rift S decided to black screen with a desktop notification "Hardware Notifcation - Meta Quest Link isn't working"

Audio worked, and the device showed green dots in the Meta app for the headset and controllers, but on putting it on the display would not light up and the notification popup was received.

I tried:

• fully uninstalling and re-installing quest apps
• upgrading graphics drivers
• unplugging all other USB devices
• trying all sorts of combinations of USB ports and Display ports

I had given up thinking it was broken but..

Today I found the linked article TLDR:

Adding a firewall rule to block OculusDash.exe from connecting outbound fixes this issue.

Hope this is some help to others who may be having the same issue.
