Someone at Oculus screwed up pretty badly today, an expired certificate appears to have soft-bricked all of the company’s Rift VR headsets with users still unable to fire up software on the devices with no word of an incoming fix from the company yet.

Issues were first reported several hours ago on Reddit, where a post on the topic has already garnered hundreds of comments. The problem seems to have resulted from Oculus failing to update an expired certificate with the update, which is now leaving users with an error message saying that the system “Can’t Reach Oculus Runtime Service.”
