I'm using TeamViewer v12 on windows since a long time and have no problem with it until this morning. 2 stations : one desktop at home and one laptop at my company. I use my laptop at work to connect on my desktop at home.
NOTE : Yesterday I probably messed up with another program : Proxifier. It had probably messed up windows socks but TeamViewer seems not to have any trouble to connect at that moment so it may not be related but I think it worth mentionning.
This morning after a fresh reboot TeamViewer can't connect to master server. (TV v12 on laptop works perfectly fine)
The log file contains some strange lines

as you can see, it seems that TeamViewer can't resolve any address therefor can't connect to master server. Oh, and only TeamViewer seems to have trouble to Internetaccess. I have no problem with every other programs.
So after some search on Internet I found some hints on what to look and what to do and on this forum I had numerous possible solution. So here are my attempt to fix it :
- I've tried to stop service and start again => No connection either
- I've tried a fresh install, and even with a previous version (from July) => No connection
- I've tried to disable IPv6 to force IPv4 DNS resolve without success
- I've change my ISP DNS by Google's one - 8.8.8.8 and even with independant French DNS to test it => No connection
- Because I can in console ping everything, I've tried to put IP of ping3 / master1-2-3-etc/ directly in etc/hosts to force resolving locally => Still no connection
- I've tried to flush socks with netsh winsock reset in console => still no connection
- I've tried to patch Windows.NET with some patch recommanded on forums => still no connection
So i'm little out of option here... Do you have any idea of what can I do to fix that ?
