Is TeamViewer Down? Live status & outage reports

Service info and troubleshooting

Can't Connect to a Remote Device

The most common reason is a mismatch between TeamViewer IDs or a wrong password. Double-check the ID the other side is sharing — even one digit off and the connection won't go through. Also confirm both devices are running the same major version: version 15 on one end and version 12 on the other often causes a handshake failure.

Session Freezes or Extremely High Latency

Lag during a remote session usually comes down to the local network, not the service itself. Run a quick speed test and check for packet loss. If you're on Wi-Fi, switching to a wired connection typically drops latency by 30–50%. Also close any bandwidth-heavy apps on both ends — video streaming or large downloads will tank session quality immediately.

TeamViewer Shows 'Not Ready, Check Your Connection'

• Restart the TeamViewer service: open Task Manager, kill all TeamViewer processes, then relaunch the app
• Check if your firewall is blocking outbound TCP connections on port 5938 — that's the primary port the app uses
• Temporarily disable third-party antivirus and try reconnecting; some security suites intercept the app's network calls
• If the issue persists on Windows, run the app as Administrator

Blank or Frozen Remote Screen

This happens when the remote machine's display driver isn't compatible with the capture method TeamViewer uses. On the remote side, go to Options — Display and switch the rendering mode from DirectX to Basic. On headless servers with no monitor attached, you'll need a dummy HDMI plug to force a display signal — otherwise the screen stays black by design.

App Crashes on Launch

Corrupted installation files are usually the culprit. Uninstall completely using the official TeamViewer uninstaller (not just Add/Remove Programs), reboot, then download a fresh installer from the official site. On macOS, also check System Preferences — Security & Privacy and make sure Screen Recording and Accessibility permissions are granted.

File Transfer Fails or Stalls

• Make sure both sides have file transfer enabled in the session permissions
• Large files over 2 GB sometimes stall — split them into smaller archives before sending
• Check available disk space on the receiving end; a full drive silently blocks incoming transfers
