    const redisConnection: RedisOptions = {
      host: `http://${process.env.REDIS_HOST}`,
      port: Number(process.env.REDIS_PORT),
      password: process.env.REDIS_PASS,
      username: process.env.REDIS_USER,
      family: 0,
      retryStrategy: (times) => {
        // reconnect after
        return Math.min(times * 50, 2000);
      },
    };

Ok using the private url string only works. But i wonder why you cannot construct using the options with all the same details

brodyEMPLOYEE

Hi sorry to bring this back up, but I'm not able to see the messages on discord, and I think many links are missing here.

What is the right solution to get a redis instance running within the same project? I'm having issues with the host being undefined.

"just like the example in the docs shows" does anyone have links to these docs please?

No worries, the links are indeed missing.

Getting ioredis setup correctly with private networking checklist -

Example -

const redis = new Redis(process.env.REDIS_URL + "?family=0");

Hi, I'm still having this exact issue.

I'm running:
ioredis 5.5.0
node 22.8.0

I'm configuring the redis instance like this:
```

const redisClient = new Redis(`${process.env.REDIS_URL}?family=0`, {
    tls: { rejectUnauthorized: false },
    lazyConnect: true,
    connectTimeout: 15000,
    retryStrategy: (times) => Math.min(times * 30, 1000),
  });

```

My redis url looks like this when I print it out: redis://default:yyBqSILlgwiYDnZOPgvQELaUAmvKLjgc@redis.railway.internal:6379

I'm using setting the REDIS_URL variable like this on railway: ${{Redis.REDIS_URL}}

Also regarding @brody's checklist, "ensure V2 runtime enabled" - I cannot see such on option on either my redis-service or my backend-service config. Is there another way to configure this?

One thing to note is that my redis service is deployed in a US region while the backend is in europe. Ofc I'd want them both in Europe but its currently not an option on the hobby plan.

Thanks in advance!

Can you please open your own help thread, a new thread would be preferable over an 8 month old thread.
