Even though this has been resolved, it would be useful to acknowledge that the AUTH was unavailable this morning. It might help others with any support cases that came in.:
This morning between around 11am GMT and 11:37 the Windy API Auth went offline.
In Chrome browsers this was visible in the console as:
Access to XMLHttpRequest at 'https://api.windy.com/api/map-forecast/v2/auth' from origin X has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
In Fiddler, it was shown as:
The server encountered a temporary error and could not complete your request.Please try again in 30 seconds.
At 11:37 GMT the Auth began working again.
