Hello @DK1,

welcome to the Nextcloud community!

see:

try this option: --o:logging.disable_server_audit=true # enable disable server audit

@scubamuc I don’t see how that solves the problem. All you’re doing is disabling the server audit, i.e. the symptom and not the cause. His problem is not the report, but this:

@DK1 Your log says:

I’m not sure if there’s any connection at all, but are you changing the Content Security Policy with Caddy? These are usually set by Nextcloud and should not be changed.

I also find the following in the browser log strange:

The browser should see an external URL, not an internal one (I think).

Is the correct Collabora URL stored in the Nextcloud settings?

See /index.php/settings/admin/richdocuments to check this.

But I’m not sure if it’s different for AIO and therefore not a problem (I don’t use AIO).

you are absolutely right… thank you for pointing that out

yeah workaround…

not at all, here is the caddy section from the compose yaml:

  caddy:
    image: caddy:alpine
    restart: always
    container_name: caddy
    volumes:
      - /opt/docker_configs/Caddyfile:/etc/caddy/Caddyfile
      - caddy_certs:/certs
      - caddy_config:/config
      - caddy_data:/data
      - caddy_sites:/srv
    network_mode: "host"

and here is my Caddyfile:

https://nextcloud.domain.com:443 {
          reverse_proxy localhost:11000
         }

No CSP changes…

changed that for testing now, no change in the behavior. Thank you for your time and the responses.
