Can't connect to remote system after upgrading to 15.1.3937

I've never had an issue connecting to the other workstation in my home.  Today I updated both workstations to version 15.1.3937 and now nothing works.  Both are Windows 10. When I bring up TeamViewer on the two machines that were updated, I get a window that says, "Please check your internet connection.  Most likely you use a proxy server and you have to enter the proper information in the options dialog box". I go into the proxy server options and select No proxy because of course I don't use a proxy server.  I then try to connect and it never does and also doesn't get an error.
