Richdocumentscode causes Error 500

[wuesti]

Ubuntu 24.04.1 LTS
nextcloud 29.0.7snap1

Nextloud Office worked for a long time. But a week ago it causes an error 500:

Es konnte keine Verbindung zum Collabora Online-Server hergestellt werden.

Failed to connect to the remote server: Server error: GET https://nextcloud.server.home/extra-apps/richdocumentscode/proxy.php?req=/hosting/> discovery resulted in a 500 Internal Server Error response

I removed and installed again richdocumentscode and richdocuments. Nothing helps.

Here are all informations I found.

nextcloud.occ config:list richdocumentscode

        "richdocumentscode": {

        }
    }
}

nextcloud.occ config:list richdocuments
