Hello
Since yesterday, I have the problem that my Teamviewer 14 reports an error (see screenshot) and I can no longer connect to other computers. (First of all - I use: Windows 10 Pro and Teamviewer 14.0.12762 Premium (see screenshot)).

I did the update on Teamviewer 14 on 13.11.2018 and with the previous versions I never had the problem.
Basically, we also have no problem with the Internet. - So far, I've tried the following solutions unsuccessfully:
1. Exit and restart TeamViewer
2. Restart the PC
3. Update the network adapter using Windows Update
4. Deactivation of the Norten Security Firewall
I ask for urgent help.
I am available for any questions.
Best regards,
Daniel
