Welcome to the Fitbit Forums @Noogajam! I'd like that you share the type of Fitbit tracker you have. How long have you been having this problem? Have you checked if the device you're using is listed here? Have you tried these syncing troubleshoots. Make sure that there isn't another bluetooth device that may be creating interference during the process.Setting up your tracker as a new device may also help you to bring it back to sync as usual. Also, make sure that your tracker is running the latest software version and your mobile device the latest version of the Fitbit app for iOs or Android device.
Hope this helps. Let me know the outcome.
