How to fix TeamViewer only LAN connections are possible [4 solutions]

Here are four solutions that might help you fix the TeamViewer only LAN connections are possible error. Try them one by one.

Solution 1. Change TeamViewer setting

First, you need to check if the TeamViewer is set to allow LAN connections only.

Step 1. On the remote computer, go to Options (in the upper right corner).


Step 2. Select General > Incoming LAN connections, and set it to “accept”.

Accept Incoming LAN Connections

Solution 2. Flush the DNS configurations

The PC experiencing the difficulty may have a DNS issue. Despite having an internet connection, it's possible that you can't resolve the TeamViewer servers' IP. We suggest deleting the DNS cache.

Step 1. Press the Win + S and type cmd. Select Run as Administrator.

Run as Administrator CMD

Step 2. In Command Prompt, type the following command one by one and hit enter to execute:

  • ipconfig /release
  • ipconfig /renew
  • ipconfig /flushdns

Flush DNS Cache

Step 3. After a minute, restart TeamViewer.

Solution 3. Uninstall the VPN client

A VPN client installation might also cause this issue. Regardless of whether the VPN client was active, the fact that it was installed made TeamViewer incompatible owing to the underlying network modifications it made. Uninstalling the VPN client may assist in resolving the problem.

On Windows, you can go to Control PanelPrograms and Features, find your VPN client and uninstall it.

Solution 4. Resort to a TeamViewer alternative
