🔴 [SOLVED] GitHub Copilot Login Problem in VS Code – Failed to sign in to GHE.com

[AliRadoan]

Hi everyone❤️,

VS Code - GitHub Copilot Error "Failed to sign in to GHE.com. You must be signed in to use AI features." ⚠️

Error Description 📝

When attempting to sign in to GitHub Copilot inside Visual Studio Code, the following message appears:

Failed to sign in to GHE.com. Would you like to try again?
You must be signed in to use AI features.

Even though the account being used is a GitHub Pro / Education account, the connection fails and Copilot stops working.

Root Cause of the Problem 🧠

This issue occurs when VS Code settings are incorrectly configured to use GitHub Enterprise Server (GHE) instead of regular GitHub.com.

In the settings.json file, the following lines appear:

"github-enterprise.uri": "https://something.ghe.com",
"github.copilot.advanced": {
  "authProvider": "github-enterprise"
}

These settings cause VS Code to attempt to sign in to a non-existent domain (ghe.com) instead of the official domain (github.com), which leads to authentication failure and the error message.

Steps to Reproduce the Problem 🔁

1. Install 📥 the GitHub Copilot extension in VS Code
2. Sign in 🔐 for the first time and mistakenly select: "Sign in with GitHub Enterprise"
3. Attempt to run ▶️ Copilot or Copilot Chat
4. Error message appears ❌: Failed to sign in to GHE.com. You must be signed in to use AI features.

Confirmed Solution ✅

Step 1: Open Settings File 📂

Open Command Palette using:

• Browser codespaces: Ctrl + Shift + P

Step 2: Search for Settings 🔍

Step 3: Remove Enterprise Settings 🗑️

Delete any settings related to GitHub Enterprise, such as:

"github-enterprise.uri": "...",
"github.copilot.advanced": {
  "authProvider": "github-enterprise"
}

Step 4: Keep Simple Configuration 📝

Make the file simple with only this configuration:

{
  "github.copilot.nextEditSuggestions.enabled": true
}

Step 5: Save Changes 💾

Save the changes:

• Ctrl + S

Step 6: Reload VS Code 🔄

Reload VS Code using Command Palette:

• Or simply restart VS Code

Step 7: Sign in Again 🔐

1. Open Command Palette again
2. Search for: GitHub Copilot: Sign In
3. Select "Sign in with GitHub" (NOT GitHub Enterprise) ⚠️
4. Complete the authentication in your browser 🌐

Step 8: Verify Copilot is Working ✨

Test Copilot by:

• Opening any code file 📄

• Copilot suggestions should appear! 🎉

Additional Tips 💡

• ✅ Always use "Sign in with GitHub" not "GitHub Enterprise"

Success! 🎉

After following these steps, GitHub Copilot should work normally in VS Code without any authentication errors!
