File corruption on html access but actual file is not

I host mostly PDF files and periodically some files are shown as corrupt when accessed via website, but the actual file is not corrupt. I receive a “Invalid or corrupted PDF file” error, “PDF.js v2.12.313 (build: a2ae Message: Invalid PDF structure.” I delete the file and replace it with a backup file. Only thing that I can think is something to do when I run a resync and rehash and it corrupts files that were fine before. Thanks!

hi
interesting - when you have a corruption displayed in the pdf viewer, are you able to actually Download the file? Or does it end up corrupted as well?

I believe it says that it is corrupt

Hi,
This issue may relate to double URL encoding, which can lead to 403 Forbidden errors when serving files with special characters (e.g., spaces, %, etc.) via a reverse proxy.

Do you have any reverse proxy?

No reverse proxy. Only symbols that are used are an occassional &, but not sure that any of the corrupt files used it. I’ll watch for that.
