That is just the source for the Leaflet script (happens to be stored on a Cloudflare CDN) .. it has nothing to do with Cloudflare being enabled for caching of pages/etc on your website -- it looks like pages/etc are not being cached on your website at this time (based on the HTTP response headers missing any of the usual cache control headers).
The problem with the forecast map script is due entirely to problems with caching BY THE NWS of api.weather.gov responses with stale data.
As I said before, this is a sporadic but long-standing problem with the NWS and data refresh to the Akamai cache servers that the NWS will have to fix.
Right now, I have a more serious data problem I've reported to the NWS API team -- the point->gridpoint lookups for MTR (Monterey/SF Bay) office seem to have a +0.5 degree latitude bias, so the forecast is coming back from the wrong place. My own page at
https://saratoga-weather.org/forecast-map.php is showing the forecast area for Saratoga lat/long as somewhere between Oakland and San Leandro, about 45miles north of me. Grrrr... Since the advforecast2.php V5.17 uses the same API, it, too, is showing a forecast that's not for my actual area.
