Installation problem on Centos Linux

[BobOfMellor]

I am trying to install TV 10 on a PC running Centos 6.6 (SELinux disabled). I persistently get the 'Sign-In request failed! The server did not respond' message, and I have not made a successful connection. Other PCs (Windows and Centos 7) on the same network connect with no problems.

I have my suspicions of the firewall, but TV say "In general, TeamViewer will always work if surfing on the Internet is possible. Hence, no firewall configuration is required.", and I can surf from this PC.

I have reinstalled TV - any suggestions on what to try next?
