The Basics

  • Nextcloud Server version (23.0.12):
  • Operating system and version (e.g., Ubuntu 24.04):
    • `raspberry OS bullseye
  • Web server and version (e.g, Apache 2.4.25):
    • 2.4.59
  • PHP version (e.g, 8.3):
    • 7.3.31
  • Is this the first time you’ve seen this error? (Yes / No):
    • yes
  • When did this problem seem to first start?
    • when I tried to access nextcloud from remote.it proxy
  • Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
    • Bare Metal
  • Are you using CloudfIare, mod_security, or similar? (Yes / No)
    • No

Summary of the issue you are facing:

When I get to the File page I see the error “Permission denied” and if I go to the admin page I have the error message Webdav is broken. I saw this error once I started to use remote.it as proxy to my Nextcloud installation.

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

  1. Install Nextcloud
  2. connect remote.it to nextcloud
  3. navigate to the File page

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.

That Nextcloud version is end-of-life since December 2022 so my recommendation is to update to a supported Nextcloud version first.

Beside that you seem to have a certificate issue which seems to prevent you from accessing the server.

You want to ride a dead horse. Get a live horse.

And also this is a dead horse. Get Debian 12.

I’m not sure the problem is the certificate since I can access the web interface (except the Photo part)
