How to debug a DOI submission error

Describe the issue or problem
I’m trying to submit DOIs to Crossref, but the task results in an error, and I can’t find any details on what failed, so I can address it.

Steps I took leading up to the issue
For example:

  1. Go to the “/dois” page in my journal.
  2. Expand an article.
  3. Click on the “Deposit DOI(S)” button. The status becomes “Sumitted”.
  4. After a minute, the status becomes “Error”, but no more information is shown.

What application are you using?
