I had been successfully getting current weather and forecasts using an ESP8266 WiFi device to drive an LED display. It suddenly stopped connecting to Weather Underground. Before I issue the HTML GET statement, I connected to IP address 18.104.22.168. This worked for weeks but stopped today. My debug statements tell me my device can't connect to that address. I tried several address like https://www.wunderground.com/weather/api/. I can connect, but the result of the GET request was HTTP/1.1 400 Bad Request. Any help would be greatly appreciated. Thanks
