It seems that Firefox does not display the error if it autocompletes the url with http://. For some reason yesterday it went via https://. If you use https:// explicitly the failure is still there.
That explains why I never see the problem.
Does apache allow for custom domain? Then it would be simply a matter of pointing the DNS record to apache server and use nuttx.org as the main URL. Also, it is good practice to make HTTP be redirected to HTTPS, if GoDaddy allows for that.
The URL is just parked and redirects. It already does redirect to https://nuttx.apache.org. There are no options for setting up the redirection other than the redirect URL.
There is a option to add DNSSEC (with a fee). it gives me these options: Key Tag, Algorithm, Digest Type, Digest. But I don't fully understand that.
I vote that we end the re-direction. It is time to break that tie.
