DNS not working

It seems DNS name resolution is not working inside latest version of TV
(12.0.71510 NI) on Linux Ubuntu Zesty Zapu.

If I go to master4.teamviewer.com by browser I can read the diagnostic message "This site is running TeamViewer."

I enclose a little part of the log file.

Any help?

    Dear Domenico,

    Thank you for your post.

    May you please try if the following command works for you?

    sudo teamviewer daemon restart

    Then open up TeamViewer again.

    Dear Domenico,

    Thank you for your message.

    Could you please update TeamViewer to the latest version v12.0.76279 from our website and try again?

    https://www.teamviewer.com/en/download/linux/

    If the problem still occurs after the update, please feel free to contact us again.

     

    Best regards,

    Christian

  • I'm having a similar problem, which seems to be caused by a bug in libcurl rather than in TeamViewer itself. With IPv6 enabled, libcurl fails to resolve various teamviewer.com hostnames: 

    No wait, it's probably a bug in systemd-resolvd. I get the same result with wget and Firefox; if I limit traffic to either IPv4 or IPv6, it works, but without either -4 or -6, resolved returns an error.

    $ curl http://router11.teamviewer.com/cname.aspx
    curl: (6) Could not resolve host: router11.teamviewer.com
    $ curl -6 http://router11.teamviewer.com/cname.aspx
