Cannot bind onto IPv6 address
I want the server to bind on an IPv6 address, and configured it like this:

```
[Server]
address = "[::1]"
```

However, this consistently fails with the following error message:

```
systemd[1]: Started Nitter (An alternative Twitter front-end).
nitter[216801]: Starting Nitter at http://nitter.example.org
nitter[216801]: Connected to Redis at localhost:6379
nitter[216801]: oserr.nim:95             raiseOSError
nitter[216801]: asyncfutures.nim:437     asyncCheckCallback
nitter[216801]: Error: unhandled exception: Additional info: Name or service not known [OSError]
```

I'm not sure what is happening from the error message here, other services that I configured to bind on the same address work just fine
