As of around 9:30 am on 11/19/2020, the NOAA plugin is returning errors. This happened simultaneously in 3 different Indigo installations with 3 different weather stations. The error is:
NOAA Weather Error HTTP error getting station KFMH data: HTTP Error 403: Forbidden
I tested the URL that the plugin uses (http://www.weather.gov/xml/current_obs/KFMH.xml) in Safari, and that also fails. I don't know if this a temporary problem, or NOAA changed the interface.
