I can't connect my Fitbit

Updated May 12, 2026 Employee

Having trouble connecting your Fitbit to Vantage Fit? Here are the most common issues and how to fix them.

Before You Start

Make sure you have:

  • The Fitbit app installed on your phone.
  • An active Fitbit account — you should be logged in to the Fitbit app.
  • Your Fitbit device synced to the Fitbit app (check that recent data appears in Fitbit).
  • A stable internet connection.

Step-by-Step Troubleshooting

Step 1: Disconnect and Reconnect

If you previously connected Fitbit but it stopped working:

  1. Open the Vantage Fit app.
  2. Go to SettingsDevice Management.
  3. Tap Disconnect next to Fitbit.
  4. Wait a few seconds.
  5. Tap Connect next to Fitbit.
  6. Complete the sign-in authorization flow — log in to Fitbit and grant permissions.

Step 2: Check Fitbit Permissions

During the connection process, Fitbit asks you to grant specific permissions. Make sure you allow all requested permissions:

  • Activity and exercise
  • Heart rate
  • Sleep
  • Profile

If you denied any permissions, the connection may not work properly. Disconnect and reconnect, making sure to grant all permissions this time.

Step 3: Clear Fitbit App Cache

Stale cache data can interfere with the sign-in flow.

On Android:

  1. Go to phone SettingsAppsFitbit.
  2. Tap StorageClear Cache.
  3. Open Fitbit, make sure you are logged in.
  4. Try connecting from Vantage Fit again.

On iOS:

  1. Delete the Fitbit app.
  2. Reinstall from the App Store.
  3. Log in to your Fitbit account.
  4. Try connecting from Vantage Fit again.

Step 4: Wait and Try Again

Fitbit limits how often apps can request your data. If you or other apps have made too many requests in a short period, the connection may temporarily fail.

Fix: Wait about an hour and try again. The limit resets automatically.

Note: This is a Fitbit-imposed limit, not a Vantage Fit limit. If you use many apps that connect to Fitbit, you are more likely to hit this limit.

Step 5: Check Your Internet Connection

The Fitbit connection requires a stable internet connection during the entire sign-in process. If your connection drops mid-flow, the connection may fail silently.

Fix:

  1. Make sure you are on a strong Wi-Fi connection.
  2. Disconnect from any VPN (some VPNs interfere with the Fitbit sign-in).
  3. Try the connection process again.

Still Not Connecting?

If none of the above steps work:

  1. Update both apps. Make sure Vantage Fit and Fitbit are both updated to the latest version.
  2. Restart your phone. A fresh start can clear temporary issues.
  3. Try from a different network. Switch between Wi-Fi and mobile data to rule out network issues.
  4. Check Fitbit server status. Rarely, Fitbit's servers may be down. Check status.fitbit.com for any outages.
  5. Contact your HR admin. They can escalate to Vantage Fit support for further investigation.
