TeamViewer Not Connecting in 2026: Troubleshooting Guide
Experiencing connection issues with TeamViewer in 2026? While TeamViewer is a robust remote access tool, connectivity problems can arise. This guide provides troubleshooting steps to help you get back online.
Basic Checks and Quick Fixes
- Verify Internet Connection: Ensure both the local and remote computers have stable internet access. A speed test (e.g., using speedtest.net) should show reasonable upload and download speeds. Minimum recommended speed for TeamViewer is 1 Mbps, but higher speeds are preferable.
- Restart TeamViewer: Close and reopen the TeamViewer application on both machines. This often resolves temporary glitches.
- Restart Computers: A simple reboot can clear up system issues that might be interfering with the connection.
- Check TeamViewer Status Page: Visit the official TeamViewer status page (search "TeamViewer status" on Google) to see if there are any known server outages.
- Firewall/Antivirus Interference: Temporarily disable your firewall or antivirus software to see if they are blocking TeamViewer. If this resolves the issue, configure your firewall/antivirus to allow TeamViewer. Specific ports used by TeamViewer are 80, 443, and 5938 (TCP/UDP).
Advanced Troubleshooting Steps
If the basic checks haven't resolved the issue, try these more advanced solutions:
- Update TeamViewer: Ensure you're running the latest version of TeamViewer on both computers. Outdated versions can have compatibility issues. You can update through the TeamViewer application itself.
- Check TeamViewer Options: In TeamViewer, go to Extras -> Options -> Advanced and review the "Network settings". Experiment with different settings, such as "Connection type" (e.g., try "LAN only").
- Proxy Server Settings: If you're using a proxy server, ensure the proxy settings in TeamViewer are configured correctly. You can find these settings under Extras -> Options -> General -> Proxy settings.
- TeamViewer ID and Password: Double-check that you are entering the correct TeamViewer ID and password for the remote computer. A single typo can prevent the connection.
- TeamViewer Blacklist: Verify that the remote computer hasn't accidentally blacklisted your TeamViewer ID.
