Fix Meta Quest Guardian Error 108 Tracking Or Boundary Not Working (2025)

Updated: 11/29/2025

You put on your Meta Quest headset, ready to jump into VR, but the Guardian system refuses to cooperate, sometimes you see Error 108 or similar messages, other times the boundary disappears, shakes, or stays greyed out in settings. The headset might insist that tracking is lost, even though the room looks fine to you. These issues usually point to tracking cameras, lighting, or software glitches rather than a broken headset, and a few careful resets often bring Guardian back to life [web:52][web:55][web:58][web:61].

Method 1: Fix Lighting And Camera Visibility First

If your play area has large mirrors, glossy windows, or repetitive textures like striped wallpaper, try facing a different direction or temporarily covering those surfaces while testing Guardian. Highly reflective or repetitive environments make it harder for the tracking system to understand where you are, which can result in constant boundary loss messages [web:61].

Method 2: Reset Guardian Boundaries And Tracking

Once the new boundary is set, hold the power button on the Quest until the power menu appears, choose Restart, and wait for the headset to fully boot back into the home environment. This soft reboot refreshes tracking services and often stops recurring Error 108 or similar boundary popups after a new Guardian is in place [web:52][web:58].

Warning: If you play connected to a PC using Quest Link, remember that changing Guardian inside Link settings can disable or override the standalone Guardian until you turn it back on from the headset side [web:55].

Method 3: Update Software And Consider A Safe Reset

If you have tried all previous steps and Guardian still refuses to work or Error 108 appears constantly, back up your important data and perform a factory reset using the power and volume buttons from the boot menu. This wipes local settings and installed apps but reloads a clean system image, which can clear deeply corrupted tracking data that no other step can fix [web:52][web:58][web:61].

Press and hold Power + Volume Down to open the boot menu, use Volume to highlight Factory reset, then press Power to confirm
