Making an API call even with the DEMO_KEY is returing 502 Bad Gateway

steps to reproduce:
execute

https://api.nasa.gov/planetary/apod?api_key=DEMO_KEY
result:

Response with status: 502 Bad Gateway for URL: https://api.nasa.gov/planetary/apod?api_key=DEMO_KEY
Using registered API key is resulting in the same status.

I'm getting similar problems with https://sscweb.sci.gsfc.nasa.gov/WebServices/REST/json/ and other APIs, is this a wider problem, did you manage to resolve it?
