Troubleshooting Authentication Issues

Authentication issues usually occur when you try to log in or connect your account to Critical Ops, resulting in an error code such as 1001, 1002, or something similar. These errors can happen when there's a problem with your login credentials or connection to your account (Google, Facebook, or Game Center). In most cases, resolving the issue involves updating your apps, clearing your cache, or adjusting your server settings.

General Steps (Android & iOS)

Before diving into platform-specific fixes, make sure of the following:

  • Your operating system is updated to the latest version.
  • You are on a stable internet connection
  • You are using the latest version of Critical Ops
