github copilot not showing suggestions: 7 Fast Fixes That…

GitHub Copilot has transformed the way developers write code, offering intelligent code completions that save hours of coding time. But what happens when this powerful tool stops showing suggestions? You are not alone. Thousands of developers have reported the frustrating issue of github copilot not showing suggestions, and it can happen to anyone regardless of experience level.

According to community discussions and support threads, this problem affects a significant portion of Copilot users. The issue typically appears suddenly, leaving developers without their trusted coding assistant. The good news is that most cases are resolved within minutes once you know what to check.

In this guide, I have compiled the most effective solutions based on real user experiences and official documentation. Whether you are a beginner or an experienced developer, you will find actionable steps to get Copilot working again. I have organized these fixes from simplest to most advanced, so you can try the quick solutions first before diving into technical troubleshooting.

What Causes github copilot not showing suggestions

Understanding the root causes helps you apply the right fix faster. Here are the most common reasons why Copilot stops providing inline suggestions.

• Outdated Software: Using older versions of VSCode or the Copilot extension is the most frequent cause. GitHub regularly updates Copilot with bug fixes and improvements, and outdated versions may fail to communicate properly with the Copilot service.
• Disabled Inline Suggestions: The inline suggestion feature might have been accidentally turned off. This can happen through keyboard shortcuts, settings changes, or updates that reset your preferences. The setting editor.inlineSuggest.enabled controls whether ghost text appears in your editor.
• Duplication Detection Enabled: GitHub Copilot includes a duplication detection feature that limits suggestions when the model detects similar code patterns. If you are working with common code patterns, this feature can significantly reduce or eliminate suggestions.
• Server Connectivity Issues: Sometimes the problem is not with your local setup but with the connection to GitHub’s servers. Network issues, VPN conflicts, or server timeouts can prevent suggestions from loading while the Copilot chat feature continues to work normally.

Quick Fix – Try This First (30 Seconds)

Before diving into complex troubleshooting, try these simple steps that resolve the issue for approximately 80% of users.

1. Check the Status Bar: Look at the bottom right corner of your VSCode window. You should see the Copilot icon. Click on it and verify that inline suggestions are enabled. If you see any disabled options, toggle them on.
2. Reload the Window: Press Ctrl+Shift+P (or Cmd+Shift+P on Mac) to open the command palette. Type “Reload Window” and select it. This refreshes VSCode and often resolves temporary glitches.

If these steps do not work, move on to the comprehensive fix guide below. The 30-second reload often fixes temporary connection issues between VSCode and Copilot servers.

Complete Step-by-Step Fix Guide

Follow these steps in order to systematically diagnose and fix the github copilot not showing suggestions issue.

1. Update VSCode to the Latest Version: Open VSCode and go to Help > Check for Updates. Download and install any available updates. An outdated VSCode version may not be compatible with the current Copilot extension requirements.
2. Update the GitHub Copilot Extension: In VSCode, press Ctrl+Shift+X to open Extensions. Search for “GitHub Copilot” and check if an update is available. Click Update if you see the option. Restart VSCode after updating.
3. Verify Inline Suggestion Settings: Press Ctrl+, to open Settings. Search for “inlineSuggest” and ensure “editor.inlineSuggest.enabled” is checked. Also verify that “github.copilot.inlineSuggest.enable” is not set to false.
4. Check Copilot Status Menu: Click on the Copilot icon in the bottom-right status bar. Look for options like “Enable Inline Suggestions” and make sure they are checked. If options are grayed out, your subscription may have expired or you may not be authenticated properly.
5. Disable Duplication Detection: Go to Settings and search for “copilot.duplication”. Uncheck any duplication detection settings that might be limiting your suggestions. This is especially important when working with boilerplate code or common patterns.
6. Sign Out and Back Into GitHub: Press Ctrl+Shift+P and type “GitHub Copilot: Sign Out”. After signing out, restart VSCode and sign back in using the GitHub authentication flow. Authentication issues often cause suggestion failures.
7. Check Your Internet Connection: Ensure you have a stable internet connection. Copilot requires connectivity to GitHub servers to generate suggestions. Try opening a browser to confirm you can access github.com without issues.

After completing these steps, open a new code file and start typing. You should begin seeing ghost text suggestions appear within a few seconds.

Advanced Fixes

If the basic troubleshooting has not resolved your issue, these advanced solutions target deeper configuration problems.

Reset Copilot Configuration:

{

  "editor.inlineSuggest.enabled": true,
  "github.copilot.enable": {
    "*": true
  }
}

Open your VSCode settings.json file (Ctrl+Shift+P > “Open Settings JSON”) and ensure these values are set correctly. This overrides any conflicting workspace or remote settings.

Check for Extension Conflicts:

Ctrl+Shift+P > "Disable All Extensions"

Then re-enable only GitHub Copilot to test if another extension is interfering. Some extensions that modify editor behavior can conflict with Copilot’s inline suggestion system.

Clear Copilot Cache:

Ctrl+Shift+P > "Developer: Clear Editor Suggestion Cache"

This clears cached suggestion data that might be corrupted or outdated. VSCode will rebuild the cache when you start coding again.

These advanced fixes target scenarios where corporate settings, workspace configurations, or extension conflicts are preventing Copilot from functioning properly. I have found that enterprise users with restricted IDE settings often benefit most from the settings.json approach.

Still Not Working? Try These Instead

Sometimes, despite all troubleshooting, Copilot may not be the right fit for your workflow. Here are alternative code completion tools that many developers have switched to successfully.

Tabnine: A popular AI code completion tool that works entirely offline once configured. It offers strong suggestions and has a free tier. Many developers prefer Tabnine for its privacy-focused approach and minimal server dependencies.

Amazon CodeWhisperer: AWS’s code completion solution that integrates well with various IDEs. It provides real-time code suggestions and includes security scanning features. CodeWhisperer is free for individual developers.

JetBrains AI Assistant: Built into JetBrains IDEs, this tool provides intelligent code completion and explanations. It offers deep IDE integration and works seamlessly with languages supported by IntelliJ-based IDEs.

If you decide to explore alternatives, consider what matters most to you: offline capability, pricing, IDE compatibility, or specific language support. Each tool has strengths in different areas.

FAQ

Why did GitHub Copilot stop showing suggestions suddenly?

This usually happens due to a VSCode update that changed settings, an extension conflict, or temporary server connectivity issues. Most cases are resolved by reloading the window or updating the Copilot extension to its latest version.

Does GitHub Copilot require an internet connection to show suggestions?

Yes, Copilot needs an active internet connection to communicate with GitHub servers and generate suggestions. If you are offline, the extension will not provide any inline suggestions, though some cached responses might still appear.

Can other VSCode extensions interfere with Copilot?

Absolutely. Extensions that modify editor behavior, add their own autocomplete features, or change keyboard shortcuts can conflict with Copilot. I recommend disabling other extensions temporarily to identify if any are causing the issue.

Is there a limit on how many suggestions Copilot can provide?

Yes, GitHub has implemented rate limits and duplication detection that can reduce the number of suggestions you receive. If you are working with common code patterns, you may notice fewer suggestions appearing.

How do I know if my Copilot subscription has expired?

Check the Copilot status in the VSCode status bar. If it shows “Copilot not authenticated” or requires re-login, your session may have expired. Visit github.com/settings/copilot to verify your subscription status and reactivate if needed.
