How do I fix TeamViewer no connection to my partner?


Hello! I installed TeamViewer for personal non-commercial use. I have Windows 10. I tried to connect to a remote computer: I entered the identifier and password. A window appeared with the message ‘Connecting’ and nothing after that, there are no more messages. I would be grateful for any help.”

- Question from TeamViewer Community


Like many tech-related platforms, TeamViewer often fails to meet its expectations. You may try to connect to a computer remotely but fail to do so and receive various connection errors, for example, “Not ready. Please check your connection”, TeamViewer ready to connect but not connecting, or TeamViewer not connecting reason unknown. Don’t worry; there are solutions to connection problems.

How to fix TeamViewer not connecting

Before answering how to fix TeamViewer not connecting, let’s figure out the reasons causing the connection problem.

  • Internet connectivity problems
  • Access settings on TeamViewer
  • Windows settings
  • Software versions

We’ll give solutions to the connection problems caused by the above three reasons respectively.

Case 1. Connection failed caused by internet connectivity problems

If there is a resource that TeamViewer highly depends on, then it is the Internet. When it comes to remote control, both devices need to have either cellular data or Wi-Fi. If TeamViewer seems problematic, your connectivity is the first thing you should check.

Go to the right-bottom corner of both desktops, and check whether WiFi or LAN is successfully connected.

Internet Setting

Case 2. Connection failed caused by access settings on TeamViewer

Sometimes, the connection may fail because the device you are trying to connect to is denying any incoming remote control sessions. You need to give full access to computers connecting to this device.

Go to Options (on the top right corner) > Advanced. Under Advanced settings for connections to this computer, choose Full Access. Besides, check Full access control when a partner is connecting to the Windows login screen box.

Case 3. Connection failed caused by Windows settings

Other settings that you need tolook atare Windows Firewall settings and the proxy settings.

Solution 1. Check Windows Firewall settings

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.
