MRIQC API service down?

I’m trying to query the MRIQC API (e.g., https://mriqc.nimh.nih.gov/api/v1/T1w) and I’m getting a “HTTP Error 502: Bad Gateway”. I am able to connect to the server itself (https://mriqc.nimh.nih.gov).
Does anybody know if the API server is down?
Thanks.

Looks like there is an issue with its database connection. Will let you know when it’s back online.

Should be up now, let me know if you see any issues with it.

It works now.
Thanks!
