Bad Signature with specific files

[jask05]

Steps to reproduce

I don't know how to reproduce but I tell you what I have.

1. Folder (Nextcloud): /Carpetas/Málaga/Para entregar/
2. Files: "Pleno Extraordinario 08-11-17 (Eva).docx" and "Comisión Transparencia 02-11-17 (Eva).docx"

If I click either this two files I've get HTTP error 503. These files are upload by a user in a shared folder and this user is not the owner of this folder.

Expected behaviour

It should download these files.

Actual behaviour

HTTP error 503

Summary

When I try to download specific files in a specific folder (with blank spaces and accents in their names) I get HTTP 503 error. These files exists in the server (physical). This is a shared folder and its owner is different than owner of the files.
I activated encryption module but I've disabled it because I got "bad data signature" error in Nextcloud web log. I thought that the problem was there but with encryption disabled it continue.

Also I could check when I get a file CPU load change from 0-2% to 80-90%.

Thanks

Wanted to comment that I have a same/similar issue. Hoping to see this get addressed.

I'm running Nextcloud 13.0

[baumimwald]

After upgrading from nc 12.0.6 to nc 13.0,1I also have the same problem. Cannot open or download files. Activating the encription app helped

[mayconritzmann]

I have the same problem, can anyone help me?

I have a same/similar issue.

[victorbw]

same here. maybe not identical, but at least similar at first sight.

running 13.0.1.

[edes]

Same here. Brand new 13.0.2 installation. Default encryption module enabled. Using Nextcloud desktop client on Linux. Problem suddenly started after up-syncing ~45GB to the "empty" cloud without any problems. Further syncing now is not possible due to a multitude of errors of this kind:
