Jarom, Thanks so much! I see what I did wrong and I was able to make a stubbed down version for basic testing to prove it's at least trying to connect.
Same location (for WeeWX 3.9.1): https://raw.githubusercontent.com/UberEclectic/weewx/master/bin/wunderfixer The thing is, I'm still constantly getting 404 (Not Found) even with CURL, and just a bit ago the site started throwing 503 (Service Not Available). So... It's kinda hard to test under these conditions. But as long as you don't get a 403, then at least my User-Agent "hack" will be "proven." :-/ Regards, \Leon -- Leon Shaner :: Dearborn, Michigan (iPad Pro) > On May 23, 2019, at 1:57 AM, Jarom Hatch <[email protected]> wrote: > > I tried the 3.9.1 version and I get Could not get Weather Underground data. > Exiting. > > Curl still works, even for yesterday's data.
