Teamviewer Unable to Connect (No Error Message).

Question

I have installed Teamviewer 9 on a Windows 7 64-bit machine and it is able to connect to other computers using Teamviewer but no one is able to connect to the machine.

I click connect and Teamviewer attempts to connect to the machine (it can be seen as online in the computer list on the right). Furthermore, when I try to enter the Options menu, Teamviewer stops responding and crashes.

It doesn't seem like a firewall issue or a machine connectivity issue as I have disabled the firewall and can even ping the machine but cannot connect through Teamviewer.

Does this sound familiar to anyone and has anyone been able to solve this issue?

Answer 1

First make sure to configure the Firewall to allow the client to connect. Secondly, go to Settings and disable Proxy and LAN connections. When configured to LAN, Teamviewer will not have the possibility to work outside your LAN, neither will accept any connections. If this is still not working, go to Teamviewer website and download the QuickSupport. The package consists of an application designed for quick support. It contains an ID and a randomly generated password.

Answer 2

This happens when you change your computer name. In other words, Connection > Setup Unattended Access and you change your computer's remote connection nickname.

It is okay to change the nickname. But then you need to open TeamViewer, click on the little man on the "Computers & Contacts" screen, add remote computer, and add the "Your ID" number on the "TeamViewer" window. That will add your remote computer back to your Computers & Contacts group.
