The Basics
- Nextcloud Server version: 28.0.14.1
- Operating system and version: Debian GNU/Linux 12 (bookworm)
- Web server and version: Apache(the docker image default)
- Reverse proxy and version: NPM v2.12.2
- PHP version: PHP 8.2.27
- Is this the first time you’ve seen this error? Yes
- When did this problem seem to first start? After installing the app
- Installation method Docker image
- Are you using Cloudflare, mod_security, or similar? No
Summary of the issue you are facing:
The Dokuwiki integration app isn’t working with my nextcloud setup.
I have a VM on Proxmox in which the nextcloud instance and the dokuwiki are installed via Docker container. The proxmox has a Nginx Proxy Manager as Reverse Proxy. There are 2 domains cloud.example.domain.com, for the nextcloud, and wiki.example.domain.com, for the dokuwiki.
Steps to replicate it:
- Have a working dokuwiki instance. In my case using docker
- Setup on the dokuwiki instance AuthPDO
- Install dokuwiki integration app on the nextcloud instance
- Configure it so it’s able to acess the dokuwiki domain
- Try access

The error seems to be caused by the “refresh” function on the app that triggers a error on the “xmlRequest” function
OCA\DokuWiki\Service\AuthDokuWiki->xmlRequest(
"wiki.getPage",
[
""
]
)
OCA\DokuWiki\Service\AuthDokuWiki->handleError(
