What Causes the TeamViewer “Not Ready Check Your Connection” Error on Windows?
This particular problem has many different causes and pinpointing the correct one may be crucial if you don’t want to try out every method on the list. This will guide you to the solution faster and that is why we decided to create the list of all possible causes located below!
Solution 1: Remove TeamViewer from the Hosts File
It’s highly likely that the TeamViewer entry in the ‘hosts’ file on your computer has been corrupted. It might show addresses and data which is completely wrong and we suggest you delete its entry. Once you reopen it, the entry will be recreated and the problem would hopefully cease to appear!
Solution 2: Change Your DNS Address
Users have said that they were able to resolve the issue simply by changing the DNS provided by your ISP (Internet Service Provider) and starting to use a different one. It can be a DNS of a computer where the issue doesn’t appear but many users simply used Google’s DNS to resolve the problem. Follow the steps below to change the DNS address on your computer!
Solution 3: Reset Winsock
“netsh Winsock reset” is a helpful command that you can use in Command Prompt to reset Winsock Catalog back to default setting or its clean state. You can try this method if you are experiencing the inability to connect in TeamViewer.
Solution 4: Don’t Use the New User Interface
User interface shouldn’t be in any way connected to TeamViewer’s internet connection but, weirdly enough, many users have reported that they were able to resolve this issue simply by reverting to the program’s old design. This can be done in TeamViewer’s settings so make sure you follow the steps below and try to resolve this connectivity issue.
Solution 5: Add an Exception for the Teamviewer_Service.exe File
Sometimes antivirus tools fail to recognize the program’s efforts to connect to the Internet as harmless and TeamViewer’s features are often blocked by it. To prove to the antivirus that the program is harmless, you will have to add it to its Exceptions/Exclusions list!
Solution 6: Allow it in Windows Defender Firewall
For TeamViewer’s features to work properly, the app needs to have uninterrupted access to the Internet and its servers to work properly. Windows Defender Firewall is often to blame in such cases and we recommend you make an exception for the Teamviewer_Service.exe executable inside the Windows Defender Firewall!
Solution 7: Disable IPv6
Disabling Internet Protocol version 6 connectivity on your computer managed to resolve the problem for many users and it’s an easy way to resolve the problem. This makes this method worthy and you shouldn’t skip it during your troubleshooting process.
Solution 8: Restart the TeamViewer Service
Stopping the TeamViewer service from running will effectively restart the whole process and many users have reported that it only took them a few minutes to get TeamViewer to work again. Before starting, make sure you have closed TeamViewer completely.
Solution 9: Reinstall TeamViewer
If all methods above fail to work, reinstalling TeamViewer is the last method which can help you resolve the problem on your computer. It should be fast and painless if you follow all the steps properly! You will also install the latest version which contains the patch to the specific issue you are having!
