I was simply trying to better understand the post by @invbob1. If the error is indeed what I asked about, the solution I posted earlier in this thread seemed to work for me and apparently for @Shigeru Suzuki. I'm left to guess what OS @invbob1 is using.
Clearing cache, turning of anti-virus and firewalls did not work for me.
I was able to demonstrate that specifying which DNS server should be used cleared the problem. Allowing Windows 10 to instead automatically obtain the DNS server brings the problem back. Is anyone reporting this issue on a Mac? Its repeatable and reproducible on Windows 10.
That explanation is also consistent with the error messages TurboTax software generated at other points where it was having trouble with DNS. The TurboTax programmer's put that "Try Again" button (noted a few posts back) for some reason. Specifying the DNS server also resolves that.
