How to Fix Copilot Internet Connection Errors in Microsoft Word

Product: Microsoft Word
Device & OS: not provided
Scenario: Attempting to use Copilot AI features in Microsoft Word while connected to an active network.
Observed behavior: Copilot displays an error stating it is not connected to the internet and refuses to function, even though the computer has full internet access.

Before you start

Verify that your computer can access other web pages in a browser, and ensure that you are signed in to Microsoft 365 with the correct account tied to your Copilot subscription.

Solution 1Recommended

Temporarily Disable VPN or Proxy Configurations

Virtual Private Networks (VPNs) and proxy servers can sometimes block Copilot from communicating with Microsoft servers, triggering a false offline error.

Network security tools may intercept the background traffic that Copilot relies on. Disabling them temporarily will help determine if the connection error is caused by a network block.

Turn off your VPN

Open your third-party VPN client and click disconnect, or go to Windows Settings > Network & internet > VPN and toggle off any active VPN connections.

Disable proxy settings

Navigate to Windows Settings > Network & internet > Proxy. Under 'Manual proxy setup', turn off 'Use a proxy server'.

Restart Microsoft Word

Close Microsoft Word completely and reopen it. Try using the Copilot feature again to see if it successfully connects.

Temporarily Disable VPN or Proxy Configurations

Check firewall permissions: If this resolves the issue, you may need to whitelist Microsoft 365 applications in your VPN or firewall settings for long-term use.

Solution 2

Clear DNS Cache and Restart Office

Flushing your computer's DNS cache forces the system to fetch fresh IP addresses for Microsoft Copilot servers.

Solution 3

Update Microsoft 365 and Seek Support

If basic network troubleshooting fails, an underlying software bug might be responsible, requiring an update or specialized assistance.

Frequently Asked Questions

Why does Copilot say offline when my internet works perfectly for browsing?

Copilot requires specific background connections to Microsoft servers. VPNs, strict firewall rules, or misconfigured proxy settings can block these specific server addresses, causing Copilot to report an offline status even if general web browsing is unaffected.

Does signing out of my Microsoft account fix Copilot errors?

Yes, signing out of Microsoft 365 in Word and signing back in can refresh your authentication token and resolve temporary synchronization or server connection errors with Copilot.

Can a corrupted Office installation cause Copilot network errors?

Yes. If core Office components are outdated or corrupted, Copilot may fail to verify your active connection. Running an Office Quick Repair or updating Microsoft 365 through the Account settings can often fix this issue.
