Given what information you have provided, I have these suggestions to resolve your problem: • Make sure your Lighthouses can see the vive • Make sure it has not entered sleep mode (movment should fix this) • Ensure your Lighthouses are properly tracking and are the proper distance away from eachother • Check if the HMD or any other VIVE components are in need of updates via the Dropdown menu In SteamVR
If these do not fix your issue, feel free to leave this topic open, I or another user will try to assist you further shortly!
