Welcome to the Fitbit Forums @Mamapiini! I recommend starting by checking out 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.
Let me know how it goes.
