Unable to connect to Upstash Redis from Fly.io app using ioredis

[mayailurus]

Hi… That sounds like it might be this classic IPv6 gotcha:

@Gerhardcit

I just solved a ioredis issue with this

export const redisClient = new Redis(env.REDIS_URL, {
  maxRetriesPerRequest: null,
  enableReadyCheck: false,
  family: 6
});

which seems to an old problem.

Hope this helps!
