When I used Open DNS, I was able to check if the DNS was functioning by visiting a test site. Does Cloudfare have such a site which indicates that it’s functioning properly?
@sandro, much thanks. Although I cannot understand why “Using DNS over HTTPS (DoH)” is No. Is it my ignorance that’s showing?
You’d need to run a local DNS proxy for DoH to work or use a browser which supports it (i.e. Firefox). I assume that is not the case here.
I always use Firefox 65.0.1 in Windows, that’s why I asked. I also use Vivaldi on occasion. In addition, I found the download page https://developers.cloudflare.com/argo-tunnel/downloads/ and will try to set it up. Thanks again.
