How to troubleshoot missing code suggestions on GitHub Copilot
Quick Answer
Missing GitHub Copilot suggestions are usually caused by subscription issues, disabled extensions, or network connectivity problems. Check your subscription status, verify the extension is enabled, and ensure you're connected to the internet to restore code suggestions.
Prerequisites
- Active GitHub Copilot subscription
- Compatible code editor (VS Code, JetBrains, etc.)
- GitHub Copilot extension installed
- Internet connection
1
Check your GitHub Copilot subscription status
Open your web browser and navigate to github.com/settings/billing. Look for the GitHub Copilot section and verify your subscription is active. If expired or suspended, click Enable GitHub Copilot to renew your subscription.
Tip
Individual subscriptions cost {{price:github-copilot}}/month while business subscriptions are $19/user/month
2
Verify the GitHub Copilot extension is enabled
In VS Code, press
Ctrl+Shift+X (Windows/Linux) or Cmd+Shift+X (Mac) to open Extensions. Search for GitHub Copilot and ensure it shows Enabled. If disabled, click the Enable button. For JetBrains IDEs, go to File > Settings > Plugins and verify GitHub Copilot is enabled.Tip
Restart your editor after enabling the extension for changes to take effect
3
Check your authentication status
Open the Command Palette with
Ctrl+Shift+P (Windows/Linux) or Cmd+Shift+P (Mac). Type GitHub Copilot: Sign In and press Enter. If already signed in, try GitHub Copilot: Sign Out then sign back in to refresh your authentication token.Tip
Make sure you're signed in with the same GitHub account that has the active Copilot subscription
4
Verify Copilot is not disabled for your file type
Check the bottom status bar of your editor for the GitHub Copilot icon. If it shows a slash or warning symbol, click it to see if Copilot is disabled for the current file type. In the popup, ensure Enable Completions is checked and the file type isn't in the disabled list.
Tip
Some organizations disable Copilot for certain file types like .env or configuration files for security reasons
5
Test your internet connection and firewall settings
GitHub Copilot requires internet connectivity to work. Test your connection by opening a terminal and running
ping github.com. If your organization uses a firewall, ensure these domains are whitelisted: *.github.com, *.githubusercontent.com, and copilot-proxy.githubusercontent.com.Tip
Corporate networks often block AI services, so check with your IT department about Copilot access
6
Clear the extension cache and reload
In VS Code, open Command Palette and run
Developer: Reload Window to restart the editor. If issues persist, try GitHub Copilot: Reset Extension to clear cached data. For JetBrains IDEs, use File > Invalidate Caches and Restart.Tip
Cache corruption can cause intermittent suggestion failures, especially after extension updates
7
Check GitHub Copilot service status
Visit githubstatus.com to check if there are any ongoing issues with GitHub Copilot services. Look specifically for the Copilot section in the service status page. If there's an outage, wait for GitHub to resolve the issue and try again later.
Tip
Service outages are rare but can affect all users globally - bookmark the status page for quick reference
Troubleshooting
Suggestions appear but are low quality or irrelevant
Write more descriptive comments and function names to provide better context. Try breaking down complex functions into smaller, well-documented pieces. GitHub Copilot works better with clear intent and good coding practices.
Copilot works in some files but not others
Check if the problematic files are in your .gitignore or have restricted file extensions. Some organizations disable Copilot for sensitive file types like
.env, .key, or .secret files.Extension shows as installed but icon missing from status bar
The extension may have failed to load properly. Try disabling and re-enabling the GitHub Copilot extension, then restart your editor. Check the Output panel and select GitHub Copilot for error messages.
Suggestions were working but suddenly stopped
This often indicates an authentication token has expired. Run
GitHub Copilot: Sign Out then GitHub Copilot: Sign In from the Command Palette. Also verify your subscription hasn't been suspended due to billing issues.Ready to get started with GitHub Copilot?
