Yes, several NOAA/NWS sites went https only but did it poorly – some of the site names are using a common certificate that doesn’t include that specific hostname in it, so attempts to ‘verify host’ fail.
I’ve had to turn off ‘verify host’ and ‘verify peer’ for programmatic access to several of the NWS sites due to that bad certificate they installed.
Hopefully, it will get fixed shortly and https will be smoothly flowing without certificate warnings.
