Good Day,

My Nginx Config:

server {
    listen 80;
    server_name cloud.mydomain.com collabora.mydomain.com wopiserver.mydomain.com;

    location /.well-known/acme-challenge/ {
        root /var/www/certbot;
    }

    location / {
        return 301 https://$host$request_uri;
    }
}

        proxy_set_header Host $host;

}

# WOPI Server
server {

        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

I tested in my internal network where cloud.mydomain.com is mapped to my server but also from outside my network since its a public available address in both cases it doesnt work. It seems to work till it reaches Finalizing Upload there it gets stuck till it fails with an Unknown Error. The Network Request Response is 504.

If you need further Infos please ask.

@butonic any ideas where the 504 might come from?
