The TeamViewer could not connect to partner error is often hard to fix because it may be caused by network limits, firewall blocks, or version conflicts. Instead of spending time checking settings or reinstalling software, switching to AnyViewer can be a simpler solution. AnyViewer uses a different connection system, so it avoids many of the server and ID issues that cause TeamViewer to fail. This makes it easier to connect without extra troubleshooting.
AnyViewer is designed to provide stable and fast remote access in different network environments. It focuses on smooth performance and strong security to keep each session safe. The interface is clean and easy to use, so even beginners can connect quickly with a security code or unattended access. It also does not trigger strict commercial use limits, which helps prevent sudden disconnections. If other fixes do not work, using AnyViewer as a TeamViewer alternative is a practical and reliable choice.
Step 1. Install and run AnyViewer on both your work and home computers. Navigate to Log in and then Sign up on the Controller computer (if you have already registered on the official website, you can log in directly).
Step 2. Fill out the sign-up form.
Step 3. You should now see that you have successfully logged into AnyViewer. Your device will be assigned to the account to which you have logged in automatically.
Step 4. On both devices, log in to the same AnyViewer account, then click One-click control for unattended remote support to establish a direct connection.
Step 5. After successfully connecting, you will see the remote desktop. Then you can control it completely and provide remote support as if you were sitting in front of it.
Disabling IPv6 on both the local and remote computers can help fix the TeamViewer could not connect to partner error. This is because IPv6 may cause network conflicts, and turning it off forces TeamViewer to use a more stable IPv4 connection.
Step 1. Press Win + R and type "ncpa.cpl" into the Run bar to open the Network Connection window.
Step 2. Right-click the available network (Usually Ethernet or Wi-Fi) > Properties.
Step 3. Uncheck the option Internet Protocol Version 6 (TCP/IPv6), and then click OK to save.
Step 4. After doing the steps above, please restart TeamViewer and try connecting again.
Note: To resolve TeamViewer connectivity issues on macOS, navigate to your network settings or use Terminal commands to configure IPv6 as Link-local only or disable it entirely. Once you apply these changes and restart your device, the software will be able to bypass the network conflicts that previously prevented a successful connection.
Sometimes, Windows Defender Firewall may block TeamViewer to protect your system. Allowing TeamViewer through the firewall can remove this restriction and help the connection work normally.
Open Control Panel, go to Windows Defender Firewall > Allow apps, click Change settings, and tick TeamViewer Remote Control Service to allow TeamViewer through Windows Defender Firewall.
Another common cause of the TeamViewer error “Partner did not connect to router” is that Full Access control is not enabled in the settings. This can happen on either the local or the remote computer. To fix it, change the Advanced settings in TeamViewer to allow Full Access.
Step 1. Go to Options (in the top right corner) on the remote computer.
Step 2. Next, select Advanced. Select Full Access from the Advanced settings for connections to this computer menu. Select Full access control when a partner connects to the Windows login screen box.
If the TeamViewer not connecting error still occurs, you may need to adjust the proxy settings. Follow the steps below to configure them properly.
Step 1. Open Control Panel again, go to Network and Internet > Internet Options. Under the Connections tab, click on LAN Settings.
Step 2. Now, uncheck the box against Use Proxy Server for your LAN and click OK.
If TeamViewer still did not connect to router, changing your PC’s DNS settings may help. An incorrect or unstable DNS address can prevent TeamViewer from reaching its servers. Using a reliable DNS can improve the connection and reduce errors.
Step 1. Open the Control Panel and go to Network and Internet > Network and Sharing Center. Then, click Change adapter settings on the left panel.
Step 2. Double-click your current network connection and select Properties.
Step 3. Find and select Internet Protocol Version 4 (TCP/IPv4), then click Properties.
Step 4. Select Use the following DNS server addresses and enter the following:
Click OK to apply the changes.
An unstable internet connection is another common cause of this error, especially for users whose ISP assigns dynamic IP addresses. When the IP changes frequently, TeamViewer may fail to establish a stable connection. Restarting your network can help refresh the connection and obtain a new IP address. Simply power off your router or modem, wait a few minutes, then turn it back on and allow the network to reconnect.
Try to re-create the TeamViewer connection to see if the problem is still present after the internet connections on both computers have been restored.
Connection issues can also be caused by using an outdated version of TeamViewer. Older clients may not work well with current servers or security updates. Check the TeamViewer menu to see if a newer version is available. Download and install the update to ensure better compatibility and stability.
Step 1. Click the menu icon > Check for new version.
Step 2. Check to see if TeamViewer is up to date on your computer. If any updates are available, update them.
If the “TeamViewer cannot connect to partner” issue continues, try resetting the Assignment settings on the remote computer. These settings can sometimes cause account or device conflicts. Many users have reported that resetting them helps restore a normal connection.

Step 2. Under "Account Assignment," click "Remove." After a few seconds, click "Assign to account" to reconfigure the settings.
Step 3. While in this section, also enable the "Manage this device" option to ensure it appears automatically in your contact list.
