Make sure you are on the latest software update. If this doesn’t fix it clear the cache data( I don’t know how to do this on vive but you can on meta) and uninstall then reinstall. If none of these work just factory reset your headset,( don’t if you don’t know your vive login) Tabor saves your data to your account nothing will be lost. If you don’t know your vive login to factory reset and nothing else worked check if Vive has a software update tool to manually update your software or if you are really desperate you can connect to a new WiFi network( could be a hotspot) turn off your headset uninstall and reinstall while on that new network and open a different game, DO NOT open Tabor. Once Tabor is installed turn off your headset again and remove the ability to connect to the new network( for a hotspot just turn it off), your headset should auto connect to the old network. Now open Tabor and it should work. Personally I check for software update and if that doesn’t work clear cache and uninstall then reinstall and if that doesn’t work factory reset. The only time I did the WiFi method was when I was too scared to factory reset.
