Question Pesk Docker running collabora online for nextcloud

[cij]

Server operating system version

Ubuntu 22.04

Plesk version and microupdate number

Version 18.0.61

Hello,

On a Ubuntu 22 server, I have installed Plesk and am also running the Docker engine. I have successfully installed Collabora Online and set up a subdomain. Additionally, I have configured the reverse proxy settings in Nginx, and everything seems to be working correctly. The subdomain is also connected with the docker on port 9980. This means that when I add the subdomain in the Nextcloud backend, the Collabora Docker version is accessible and recognized as the correct Docker version. On the Docker itself, I can also access the Collabora admin interface without any issues.

However, when I try to open a document inside Nextcloud, I get the following error message:

Loading the document failedThe socket connection could not be established or was unexpectedly closed. The reverse proxy might be misconfigured. Please contact the administrator. For more information on proxy configuration, visit Proxy settings — SDK https://sdk.collaboraonline.com/ documentation

It seems that I have made a mistake in the configuration. I have deactivated Apache for the subdomain and am running only Nginx with the following additional settings:


# static files

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

I have tested a lot of different settings but get not running the setup. Maybee anyone can help with this issue?
