Comment 5 for bug 1646728

I also have the exact same issue. I have been using my Weather Underground api key for years and this problem just started happening in March of 2019.

I checked the URL in the output of my terminal in my browser and the json page said: "key not found".

According to Weather Underground at: https://www.wunderground.com/weather/api/

"To improve our services and enhance our relationship with our users, **we will no longer provide free weather API keys as part of our program.** If you have been directed to download our Weather Underground free API key by a third party provider, please contact your vendor for resolution."

According to: https://apicommunity.wunderground.com/weatherapi/topics/end-of-service-for-the-weather-underground-api

If you are currently operating a PWS and uploading data, you can get a new API key for free. If you do not operate a PWS that uploads data, then you have to pay for a new key and free keys are no longer available to developers and users.
