New weather module (develop branch) not updating

[rts58]

I’ve noticed recently that the new weather module in the develop branch stops updating. I got this error in the developer console:

2cors-anywhere.herokuapp.com/https://api.darksky.net/forecast/mykey/mylatlong?units=us&lang=en Failed to load resource: the server responded with a status of 503 (Service Unavailable)
0.0.0.0/:1 Failed to load https://cors-anywhere.herokuapp.com/https://api.darksky.net/forecast/mykey/mylatlong?units=us&lang=en: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://0.0.0.0:8080' is therefore not allowed access. The response had HTTP status code 503.

If the service is unavailable shouldn’t the weather module update once it is available?

If I restart MM, the module will update properly and work for about a day.
