Do you have configured the whitelist on your computer? This could be the reason, why you got this message.
Please try this:
Open your local TeamViewer options --> go to security --> black & whitelist Now you should see a TeamViewer ID or emailaddress of a TeamViewer account. (If you like, you could also remove the whitelisted partners)
Please click on Add to open your whitelist and select Manually add contact to your whitelist
Here you could allow access for TeamViewer Account via emailaddress or you may add only the TeamViewer ID of your mobile device.
To find your TeamViewer ID on your mobile device, please open the remote app and go to the advance options via gear wheel.
All the best! Reyhan
