Redis using the private connection

Hi Railway Support Team,

I’m encountering an issue when trying to connect to Redis using the private connection within my project.

Here are the details:

  • I’m using the REDIS_PRIVATE_URL environment variable provided by Railway.

  • My NestJS service and Redis plugin are in the same Railway project.

  • The Redis connection string is something like:

    redis://default:<password>@redis.railway.internal:6379

  • When I try to connect using ioredis, I receive the following error:

[ioredis] Unhandled error event: Error: getaddrinfo ENOTFOUND redis.railway.internal

t seems like the internal hostname redis.railway.internal is not resolving from within my API service container.

Can you help me confirm:

  1. Whether the Redis plugin is properly linked to my service?

  2. If there are any known DNS issues or misconfigurations preventing the service from resolving internal domains?

Let me know if you need access to my project or specific service IDs.

Thanks in advance!

Best regards,

Can you provide the snippet in which you are instantiating the redis class? (const redis = new Redis)

Hey, you have to use family: 0 during the initialization of Redis class.

Like so if you use NodeJS:

I've had the same problem and I was able to solve it that way.
