TeamViewer is a popular remote access tool that lets you control computers and devices from anywhere. But when it stops working, it can be frustrating. Common problems include connection failures, error messages, and access issues.
Check Your Internet Connection
TeamViewer needs a stable internet connection on both devices. If you're having trouble connecting:
- Test your internet speed on both computers
- Try switching from Wi-Fi to Ethernet for a more stable connection
- Avoid public networks that might block remote access software
- Make sure both devices have uninterrupted internet access
Update TeamViewer
Outdated software is a common cause of connection problems. TeamViewer releases regular updates with bug fixes and improvements.
To update TeamViewer:
- 1.Open TeamViewer on your computer
- 2.Click Help in the top menu
- 3.Select Check for new version
- 4.Follow the prompts to install any available updates
Always keep both the local and remote computers updated to the same version for best compatibility.
Adjust Access Settings
If you see "This partner does not accept incoming connections!" or similar messages, the remote device is blocking access.
To fix this:
- 1.Open TeamViewer on the computer you want to access
- 2.Click Extras in the top menu
- 3.Select Options
- 4.Go to the Advanced section
- 5.Click Show advanced settings
- 6.Under Access Control, choose Full Access from the dropdown
- 7.Click OK to save changes
This allows remote control with just the ID and password.
Restart TeamViewer Services
Sometimes temporary glitches can cause connection problems. Restarting TeamViewer often resolves these issues.
- 1.Close TeamViewer completely on both devices
- 2.Open Task Manager (Ctrl+Shift+Esc on Windows)
- 3.End any TeamViewer processes still running
- 4.Restart TeamViewer on both computers
- 5.Try connecting again
Check Firewall and Security Settings
Firewalls and security software can block TeamViewer connections. Make sure TeamViewer is allowed through your security settings.
On Windows:
- 1.Open Windows Security
- 2.Go to Firewall & network protection
- 3.Click Allow an app through firewall
- 4.Find TeamViewer in the list and make sure it's checked
- 5.If it's not listed, click Change settings then Allow another app
Solve Specific Error Messages
"WaitForConnectFailed" Error
This usually means TeamViewer can't establish a route to the remote computer. Try these fixes:
- Update to the latest TeamViewer version
- Restart both devices
- Check if both computers are on the same network type (home/work/public)
"Connection Failed (No Route)"
This error occurs when TeamViewer can't find a path to connect to the remote device:
- Verify both devices have internet access
- Try connecting with a different network
- Check if your license allows the connection (free users have limitations)
Keyboard or Mouse Not Working
If you can connect but input devices don't work:
- Try sending Ctrl+Alt+Del through TeamViewer's menu
- Check that remote input isn't disabled in the settings
- Restart the remote session
When All Else Fails
If you've tried these solutions and TeamViewer still isn't working:
- Visit TeamViewer's official support page for specific error codes
- Check TeamViewer's status page for any service outages
- Consider temporary alternatives like Windows Remote Desktop or Chrome Remote Desktop
- Reinstall TeamViewer as a last resort
Most TeamViewer connection issues can be resolved with these troubleshooting steps. Start with the simplest solutions like checking your internet and updating the software, then move to more advanced settings if needed.
