Hi, pretty much useless to try to contact Weather Underground support, I don't think it exists anymore. I think they have one person named Victoria that provides support, and looks like they dropped support all together for Webcams. I had my webcams up running for years, and all of a sudden they just stopped working a few months ago. If you do get a response from them it will probably be a form email like I received below. I received this same response three times already no matter what I ask them.

Hi!
Unfortunately, we have only very limited support for webcams.
Things to check (any or all can become corrupted):
-- The upload key (not your account password) for the cam is in place, matching the one on My Devices exactly.
-- Upload type is set to Binary.
-- Access is via webcam.wunderground.com not any IP addresses.
-- Schedule for uploads is what you want, ideally set for no less than once per minute, and probably better at once every 5-15 minutes.
Be sure that all firmware is up to date. We occasionally update our web protocols to eliminate older, out of date requests, and systems that have not been kept up to date may no longer work.
After that, I would suggest giving everything a reboot, to make sure all the information is pushed through.
Thank you for being part of the Weather Underground community!
