Copilot Suggestions Not Showing Up Fix 2026

GitHub Copilot has become an essential tool for developers seeking to accelerate their coding workflow. When Copilot suggestions suddenly stop appearing, it can significantly impact productivity. This guide provides comprehensive troubleshooting steps to restore Copilot functionality in 2026.

Diagnosing the Problem

Before applying specific fixes, determine whether the issue affects all files or specific project types. Open a new file in a different programming language and test whether suggestions appear. This isolation helps identify whether the problem stems from project-specific settings or a broader configuration issue.

Check the Copilot status indicator in your IDE status bar. A gray or disabled icon typically indicates that Copilot is not actively providing suggestions. Some IDEs display tooltip messages that reveal the underlying cause when you hover over the status indicator.

Verify Copilot Subscription and Authentication

Copilot requires an active subscription for most users. Navigate to GitHub Settings > Copilot and confirm your subscription status. If your trial has expired or payment failed, suggestions will stop appearing until you renew your subscription.

Authentication issues commonly cause suggestion failures. Open your IDE’s Copilot settings and verify you are signed into the correct GitHub account. Sign out and sign back in to refresh the authentication token. For Visual Studio Code, access this through the Accounts menu in the bottom-left corner.

Check Editor Compatibility and Extensions

Ensure your IDE or code editor supports Copilot and is running a compatible version. GitHub Copilot supports Visual Studio Code, Visual Studio, JetBrains IDEs, and Neovim. Running outdated versions may cause suggestion failures.

Update your IDE to the latest version and reinstall the Copilot extension if necessary. For VS Code, access Extensions > GitHub Copilot and check for updates. If problems persist, disable and re-enable the extension or perform a clean reinstallation.

Examine File-Type and Language Settings

Copilot provides suggestions based on file context and language detection. Verify that Copilot is enabled for the specific file type you are working with. Open Copilot settings and review the language-level configuration to ensure nothing is inadvertently disabled for your target language.

Some projects use .copilotignore files to exclude certain files or directories from suggestion generation. Check if such a file exists in your project root and review its contents. Files matching patterns in .copilotignore will not receive inline suggestions.

Review Context and Completions Settings

Copilot relies on surrounding code context to generate relevant suggestions. If your file is nearly empty or contains only comments, suggestions may be limited or absent. Ensure your code file contains sufficient context for Copilot to analyze.

Check the Completions settings in Copilot preferences. The suggestion delay, inline completion toggle, and ghost text settings all affect whether and how suggestions appear. Verify that automatic inline completions are enabled rather than requiring manual activation.

Network and Proxy Configuration

Copilot communicates with GitHub servers to generate suggestions. Corporate firewalls, VPNs, or misconfigured proxy settings can block this communication. Test your network connection by visiting api.github.com or attempting to fetch Copilot-related resources.

If you use a proxy, configure your IDE’s proxy settings to allow Copilot traffic. For VS Code, add proxy settings to your user or workspace settings JSON file. Ensure exceptions exist for GitHub’s Copilot endpoints if your proxy performs SSL inspection.

Disable Competing Extensions

Other coding assistants or extension-based AI tools can conflict with Copilot. Temporarily disable competing extensions such as Tabnine, Amazon CodeWhisperer, or IntelliCode to determine if they interfere with Copilot’s operation. Extension conflicts may prevent Copilot from registering suggestion handlers correctly.

Check File Encoding and Line Endings

Corrupted file encoding or inconsistent line endings occasionally cause suggestion failures. Verify your file uses standard UTF-8 encoding. Reopen the file if you suspect encoding issues, or save it with explicit UTF-8 encoding to reset the file state.

Examine GitHub Copilot for Business Settings

If you use Copilot for Business through an organization, administrators may have configured policies that restrict suggestions in certain repositories or environments. Contact your organization’s GitHub administrator to confirm your access permissions and any applicable restrictions.

Organization-level policies may require explicit enrollment of repositories or users. Verify that your account and project are properly enrolled in the organization’s Copilot program if such policies exist.

Clear Local Cache and Reset Settings

Local cache corruption can cause unexpected behavior. Clear Copilot’s local cache by navigating to your IDE’s application support directory and removing Copilot-related folders. After clearing the cache, restart your IDE to allow Copilot to rebuild its local data.

Resetting Copilot settings to defaults can resolve configuration-related issues. Export your current settings if you have custom configurations worth preserving, then perform a settings reset followed by a restart.

Test with Sample Code

Create a minimal test file with common patterns such as a function definition, loop structure, or class skeleton. Paste standard boilerplate code that typically triggers Copilot suggestions. If suggestions appear in this test file but not in your actual project, the issue relates to your project configuration rather than Copilot itself.

Conclusion

Copilot suggestion failures typically stem from authentication issues, subscription status, editor configuration, or network problems. Systematically eliminate potential causes by working through these diagnostic steps. Most users find that checking subscription status and re-authenticating resolves the majority of cases.

If suggestions remain unavailable after exhausting these troubleshooting steps, consider reaching out to GitHub Support with details about your environment, IDE version, and any error messages you have observed.
