Hi, after analyzing what can be done, it looks like the domain https://www.ipcamlive.com/ does not allow your webcam to be shared or process into other sites/domain including to Windy. Your video streaming service type for https://www.ipcamlive.com/ I think is basic.
You will required a video streaming subscription fee for https://www.ipcamlive.com/ to allow your webcam to be shared into other sites/domain including to windy. If you can upgrade the video streaming service type to standard, your webcam should be online on Windy again without needing to update the image URL on windy. Subscription fees for ipcamlive here https://www.ipcamlive.com/pricing.
Your lifetime snaps on Windy is on the 17th of February, May, August and November. Your next lifetime snaps is this Saturday so I strongly encourage you to upgrade the video streaming service type to standard as soon as possible before late morning on Saturday in your local time.
Cheers,
Thuan.
