Issue Symptom 

Error message received: “(Error 403) We could not authenticate with our servers. Please try again.”

Conditions

You receive the error 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.

Tip 1: Check your Sideline app version

If the version does NOT show 12.39 (iOS) or 12.40 (Android), you will need to update Sideline, as you are not on the most recent version. Here's how to check what version you're on: 

iOS

1. Open Apple app store. 
2. In the search bar, type Sideline to locate the app.
3. Select Sideline to open the app details. 
4. Under "What's New", select "Version History". 
5. Your current Sideline app version will be displayed at the top of the list. 
   
   • You need to be on version 12.39

Android

1. Open Google Play Store. 
2. In the search bar, type Sideline to locate the app.
3. Select Sideline to open the app details. 
4. Tap "What's New" to open. 
5. Scroll to the bottom to view 'App Info'
6. Your current Sideline app version will be displayed next to 'Version'
   • You need to be on version 12.40

Web

There is no app version when using Sideline Web. If you receive this error, please refer to Tip 2 below. 

Tip 2: Update to the current Sideline version

iOS & Android

1. Update your application to the most recent version that is available from the app store
2. If step one does not fix the error, uninstall Sideline from your device, then reinstall.
3. Attempt to log in to Sideline or create an account again. 

If there are no errors or issues with updating Sideline to version 12.36, you should be able to log into Sideline since you are now up-to-date on the app store version. 

However, if you are still receiving an error, cannot log back in, or create an account after updating or reinstalling Sideline, this means that you will be unable to use Sideline 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 Sideline does not support. Your device must meet the following OS versions in order to use Sideline:

• iOS: 15 or above.
• Android: 7.0 or above.
