Images stopped working

I used to have working images on my gatsby site. They stopped appearing at some point.

query:

        cover_thumbnail {
          public
          shareUrl
        }

mdx:

<img src={article.cover_thumbnail.shareUrl + "?download=true"} />

Is it due to some 8base updates? or did they expire?
How do I fix it?

Hello!
Could you provide console/network logs from devtools from the moment you try to query pictures at your client-side?
