Question

SpaceX API no longer available?

As of today, the SpaceX API to be used in the tutorials seems to be no longer available.

When configuring the data source:"The Record Data Source returned an error.

Title: Connection failed

Detail: HTTP/1.1 404 Not Found

Message: Could not authenticate with the connected system or connect to the external system at the specified URL"

Calling https://api.spacexdata.com/v4 in a browser gives me “not found”.

Calling https://spacexdata.com/ in a browser gives me “This site can’t be reached

Check if there is a typo in spacexdata.com.

DNS_PROBE_FINISHED_NXDOMAIN”.

    I tried calling one of the endpoints (https://api.spacexdata.com/v4/launches) and was able to retrieve the data successfully. 
    However, when accessing the base URL directly, it returns a 'Not Found' error.
    As a quick workaround, you can use the V3 version of the API (https://api.spacexdata.com/v3/) instead of V4, it appears to be working fine.

    The SpaceX API domain issues appear to be DNS-related rather than the API being permanently discontinued, This issue was brought.
