Say, we need a tester who is still on 3.9.1 or there abouts to try this out:
https://raw.githubusercontent.com/UberEclectic/weewx/master/bin/wunderfixer Can't do anything to workaround WU's sporadic 404 and 503 errors, but at least the 403 error should be gone. I was able to test the 4.0 / development version myself on both Python2 and 3, so hopefully Tom will merge that soon. It's over here if you are impatient. =D https://raw.githubusercontent.com/UberEclectic/weewx/development/bin/wunderfixer Regards, \Leon -- Leon Shaner :: Dearborn, Michigan (iPad Pro) > On May 22, 2019, at 7:24 PM, Leon Shaner <[email protected]> wrote: > > Hey WeeWX'ers!!! =D > > I have a fix in the hopper. > > There's nothing that can be done for the occasional HTTP 404, or even 503's I > am now seeing, but the HTTP 403 was due to a change on WU's part where they > are rejecting certain HTTP User-Agent strings.
