My girlfriend just got a new Lenovo 710, and wanted me to help set things up. As I am away at the moment, I got her to download TeamViewer, intending to log in and help her. I regularly (successfully) remote control her old laptop whenever it's needed, so I was looking forward to doing the same with this one as well.However, once she got TeamViewer set up with unattended access, and we were able to see each other as online, I tried logging in using the 'unattended access' password, but I got the error mentioned in the title.

Remove all TeamViewer or Take Control entries; Enable Take Control for an individual device on the Dashboard: Login to the Dashboard; Right-click on the target device in the north panel and choose Edit Workstation or Edit Server; Select Remote Access Change the Setting in the Take Control Configuration section to On; OK to save changes.

These are the following things I tried next, all of which still led to me getting that error:. Have her restart TeamViewer. Restart my own TeamViewer. Have her restart her computer. Try remote controlling in with her 9 digit TeamViewer ID and the random password. Have her re-enter/update the unattended access data (name and password), and try logging in again.When all that failed, I tried logging into her old laptop, and I got in like I always do.

1. May 11, 2013  News: Welcome to the Teamviewer forums, a group of Teamviewer users here to help each other. Unable to connect - A connection could not be established. Reason unknown. I've reinstalled TeamViewer here on my Laptop - I got connection number without dots between numbers and number does not look like IP address. Can you guys please try to.
2. The best approach to switch your router/modem off and on again, then wait for the connection to be re-established. After the internet connection on both computers has been re-established, try to re-create the TeamViewer connection and see if the same issue is still occurring. If you’re still seeing the “Partner did not connect to router” error, move down to the next method below. Method 3: Using the Teamviewer desktop app on both computers.

So it wasn't that her network had suddenly decided to block TeamViewer's ports.I then had her try and log onto my computer from her new laptop instead, and that worked too. She was able to move my cursor and click on things. So, somehow, incoming TeamViewer connections were being blocked.I had her check Windows Firewall to see if TeamViewer was an allowed app, and it was.

So it wasn't that.I had her check Windows Defender, and it was apparently already turned off.That reminded me that she got the laptop with Webroot installed by Best Buy's Geek Squad as part of this 2 year protection package she opted for. So I had her temporarily disable Webroot's shields to see if that was what was blocking TVr but no. Still couldn't log in. Kept getting 'Unable to connect: A connection could not be established. Reason unknown.'

I then had her try to log into her new laptop from her old laptop, which worked. So maybe only computers on her LAN are able to log in? Based on that assumption, I had her check TeamViewer's Network Settings to see if incoming LAN connections were set to be accepted exclusively, but, alas, no. It was deactivated.

Another theory down the drain.I'm at my wit's end with this now. Does anybody have any idea what might be happening?
