Unable to get weather data with lua application

[avidz]

Hello,

Our application uses lua https.request (luaSec) to retrieve weather data. This is our typical url:

graphical.weather.gov/xml/sample_products/browser_interface/ndfdXMLclient.php?product=time-series&temp=temp&pop12=pop12&wspd=wspd&lat=37.389231543994&lon=-121.90482765955&begin=2021-01-27T03:36:10&end=2021-01-28T03:36:10

It's been working fine, but lately, it ceased to get any data. There is no response, not HTTP status.
We've added User-Agent to the request header and it didn't help.

Thank you very much for your help.
