Quick Answer: How to Fix the GitHub Authentication Error<\/h2>\n

If your IDE is throwing the error “signing in to github failed. could not reach github to verify the selected account.”<\/strong>, it means your code editor cannot successfully open or complete the browser-based OAuth authentication flow. To fix this immediately:<\/p>\n

    \n
  • Update Your IDE:<\/strong> Ensure Visual Studio or VS Code, along with the GitHub Copilot extension, is updated to the absolute latest version. Older extensions have broken OAuth integration.<\/li>\n
  • Check Proxy\/Firewalls:<\/strong> Your corporate VPN or firewall may be blocking https:\/\/github.com\/login\/device<\/code>. Disable your proxy temporarily in your IDE settings.<\/li>\n
  • Clear IDE Auth Cache:<\/strong> Remove stale authentication tokens. In Windows, go to your %LOCALAPPDATA%<\/code> folder and clear your IDE’s specific identity or Copilot cache folders.<\/li>\n
  • Use Default System Browser:<\/strong> Ensure your IDE is set to launch your default operating system browser rather than relying on a bundled internal renderer.<\/li>\n<\/ul>\n<\/section>\n

    <\/p>\n

    Connecting your GitHub account to your preferred Integrated Development Environment (IDE) like Visual Studio, IntelliJ, or VS Code is usually a seamless experience. However, an increasing number of developers are running into a frustrating roadblock when trying to activate GitHub Copilot or link their version control. The dreaded popup reads: “signing in to github failed. could not reach github to verify the selected account.”<\/em><\/p>\n

    This error is entirely different from a simple “wrong password” git push failure. Instead, it indicates a communication breakdown between your IDE’s internal request handling and GitHub’s OAuth device authorization servers. Whether it is caused by strict corporate firewalls, outdated IDE plugins, or corrupted identity caches, we have the step-by-step solutions to restore your access.<\/p>\n

    Why This Specific GitHub Login Error Happens<\/h2>\n

    To understand the fix, you must understand the cause. GitHub Copilot and modern IDE syncing do not use your standard SSH key or Personal Access Token (PAT). They require a special browser-based OAuth login (Device Flow). The error triggers when:<\/p>\n

      \n
    • The Device Code Fails to Generate:<\/strong> Your IDE attempts to ping GitHub for an authorization code, but your local network drops the request.<\/li>\n
    • Browser Launch Failure:<\/strong> The IDE attempts to open the default web browser, but operating system permissions or custom JDKs (in IDEs like IntelliJ) block the launch.<\/li>\n
    • Account Mismatches (Run-As Issue):<\/strong> If you launch Visual Studio elevated (Run as Administrator) under a different Windows user profile than your active session, the authentication bridge breaks.<\/li>\n<\/ul>\n
