Next check that your server has the port 80 and 443 open
```bash
$ sudo ufw status

...
80 (v6) ALLOW Anywhere
443 (v6) ALLOW Anywhere

Sometimes we get asked "Why are you only supporting Ubuntu 20.04 64-bit?". The answer is based on choosing quality over quantity. Long ago we concluded that its better for the project to have solid, well-tested, well-documented installation for a specific version of Linux that works really, really well than to try and support may variants of Linux and have none of them work well.
At the moment, the requirement for docker may preclude running 2.6 within some virtualized environments; however, it ensures libreoffice runs within a restricted sandbox for document conversion. We are exploring if we can run libreoffice within systemd (such as systemd-nspawn).
