Does Nitter support connecting to an IPV6 Redis Instance?
Hey there, I'm trying to setup Nitter on [fly.io](https://fly.io) which extensively uses IPV6 addresses and hostnames for resolution. I am deploying using the `zedeus/nitter` image on Docker which is then configured to connect to one of Fly's [managed Redis instances](https://fly.io/docs/reference/redis/) via a private IPV6 hostname and password.

However, each time I try to launch Nitter via Fly I get a message like: `Failed to connect to Redis.` I am able to connect to this instance via redis-cli while connected to Fly's VPN tunnel but found a couple of threads on their website indicating folks also had issues connecting their apps to Redis due to it using IPV6. Is there a limitation around IPV6 addresses with Redis?

Snippet of my `nitter.conf`:

```
[Cache]
listMinutes = 240  # how long to cache list info (not the tweets, so keep it high)
rssMinutes = 10  # how long to cache rss queries
redisHost = "REDACTED.upstash.io"  # Change to "nitter-redis" if using docker-compose
redisPort = 6379
redisPassword = "REDACTED"
redisConnections = 20  # connection pool size
redisMaxConnections = 30
```
