APOD API timing out

[vegerot]

For the last few minutes, my APOD api calls have timed out:

I have been facing this same issue with the APOD api. Getting a 504 Gateway Timeout Error. Although platforms like IsItDownRightNow are saying the APOD server is up and reachable now.

https://www.isitdownrightnow.com/api.nasa.gov.html is saying access denied and I can't access using my key here, too.

The same. The server does not respond in 1 minute timeout
