I found the culprit for this: it ends up that I have used old key and base URL (before integration with windy.com). It worked fine few months but not any more. With new key and new base URL: https://api.windy.com/api/webcams/v2/, everything works fine.

Hello, thank you for asking.
If you have a link to Windy.com on your website already, it is not necessary to have another mention of Windy below your FB or instagram posts.
