When trying to add books from Content Server's browser UI, I almost always get "413 Request Entity Too Large" error. The entirety of the error message looks like:
Code:
Failed to upload the file: fyodor-dostoevsky_crime-and-punishment_constance-garnett.epub
Failed to communicate with "/cdb/add-book/2/n/fyodor-dostoevsky_crime-and-punishment_constance-garnett.epub/Calibre", with status: [413 (error)] Request Entity Too Large
413 Request Entity Too Large
nginx/1.18.0 (Ubuntu)
The books I have been trying to upload are no larger than normal, and I can add them through command-line or Calibre's desktop UI just fine. And I think I might have successfully uploaded 2 books or so in the past, but mostly the uploading just fails with the above message.
