Screenshots

If applicable, add screenshots to help explain your problem.

Environment (please complete the following information):

• OS: Synology NAS / Docker
• Calibre-Web version: 0.6.21
• Docker container: [LinuxServer]:
• Browser: Firefox 123.0

Additional context Access is via reverse proxy. The same epub file added to the same database by dragging and dropping into Calibre application is not corrupt, i.e I am confident that te source epub file is valid.

Update: this turned out to be a DRM issue, I was using the wrong AdobeID. Apologies for the false alarm ;-)
