I haven't been able to connect using any version of TeamViewer 14 on two HP laptops running Windows 10. I get:
Please check your internet connection. Most likely you use a proxy server and you have to enter the proper information in the options dialog.
I'm not using a proxy.
I got round the problem by using TeamViewer 13, but now that's about to be deprecated. This means that unless I can get TeamViewer 14 working it will be a sad goodbye to TeamViewer. If the problem with TV 13 can't be resolved can it at least be made possible to continue using TeamViewer 13?
