(Error 403) We could not authenticate with our servers. Please try again.

Issue Symptom 

The error message “(Error 403) We could not authenticate with our servers. Please try again.” is received when attempting to create or log into your Sideline account.

Cause & Resolution 

You're receiving this login-specific error because you are not running the most recent version of Sideline from the app store or have a caching issue while using our web version. To help get you logged back in or create an account, we have some tips you can try.

Mobile Steps

1. Update the Sideline app to the most recent version available from your app store (then try to create or login again)
2. If the step above does not fix the issue, uninstall Sideline from your device, then reinstall from the app store.
3. Attempt to log in to Sideline or create an account again. 

If you are still receiving an error and cannot log back in or create an account after updating or reinstalling Sideline from the app store, you will be unable to use the app moving forward.

Why?

You are most likely running an unapproved version of Sideline that is not from your app store or have an old OS version on your device that we do not support. Please check the Minimum Device Requirements article for the minimum phone OS version we require to download and use the Sideline app.  

Web Steps

1. Please clear the browser cache & cookies.
2. Reload Sideline Web (if needed, you can close your browser window and re-launch Sideline Web again).
3. If you continue to run into problems, please contact support.
