DocsViewer timing out

[candelariajr]

DocsViewer wont preview documents. URLs are all publicly visible.
Everything is up to date.

This is how the documents display:
It’s also not happening to all documents, just a select random few. File size seem to not matter. It happens to files sized less than 25MB.

After retrying- it just keeps refreshing over and over.

It generates a request to the following URL (Network inspection in web debug mode)

Which returns a reply of Code 400.

I’m not sure why it’s doing this.
