Nextcloud 33.0.7 Cannot decrypt this file, probably this is a shared file. Please ask the file owner to reshare the file with you

There is a Nextcloud server (version 33.0.7). An issue has arisen when downloading certain files dating back to 2023. In the Windows 11 client and the Google Chrome browser, the following message appears: “Cannot decrypt this file, probably this is a shared file. Please ask the file owner to reshare the file with you.”

Operating System: Ubuntu 24.04 LTS

Nextcloud 33.0.7

php -v PHP 8.2.29 (cli) (built: Jul 3 2025 13:08:18) (NTS)

apache2 -v Server version: Apache/2.4.63 (Ubuntu)

An attempt was made to remove and reconfigure the data sharing, but this did not resolve the issue. The server was not rebooted after the Nextcloud installation was updated.

We need more information, since there are multiple possibilities. Please use the support template, as indicated in your original post.

The Basics

  • Nextcloud Server version (e.g., 29.x.x):
    • 33.0.7.1
  • Operating system and version (e.g., Ubuntu 24.04):
    • Ubuntu 24.04 LTS
  • Web server and version (e.g, Apache 2.4.25):
    • Apache/2.4.63 (Ubuntu)
  • Reverse proxy and version _(e.g. nginx 1.27.2)
    • NO
  • PHP version (e.g, 8.3):
    • PHP 8.2.29 (cli) (built: Jul 3 2025 13:08:18) (NTS)
  • Is this the first time you’ve seen this error? (Yes / No):
    • Yes
  • When did this problem seem to first start?
    • 08/13/2025
  • Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
    • Classic installation
  • Are you using CloudfIare, mod_security, or similar? (Yes / No)
    • NO

Summary of the issue you are facing:

When trying to download files from a user, an error occurs: "Cannot decrypt this file; this is probably a shared file. Please ask the file owner to reshare the file with you." The problem persists after executing the decrypt-all command. This folder was previously shared with other internal Nextcloud users.After the files were decrypted, a message appeared stating that some files could not be decrypted. However, I am unable to download even the files that were successfully decrypted.

Steps to replicate it (hint: details matter!):

Tips for increasing the likelihood of a response

  • Use the preformatted text formatting option in the editor for all log entries and configuration output.
  • If screenshots are useful, feel free to include them.
    • If possible, also include key error output in text form so it can be searched for.
  • Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
