Cannot connect to Redis via Private Network

In my nodejs app I create a BeeQueue instance like:

const eventProcessingQueue = new BeeQueue(`queue_name`, {
  redis: { url: appSettings.redisConnectionString },
});

const eventProcessingQueue = new BeeQueue(`queue_name`, {
  redis: { url: appSettings.redisConnectionString },
});

appSettings.redisConnectionString is set - correctly - to the internal Redis URL, but when trying to deploy (after successfully building), I get Redis connection to redis.railway.internal:6379 failed - getaddrinfo ENOTFOUND redis.railway.internal. Switching to the public URL, works fine. Tried appending family=6 (and 0 which is the default) at the connection string. Also tried creating a redis client and seting the socket family to 6 but then it fails for another reason (trying to connect to localhost). I also have setup a sleep when starting. The service I'm connecting from and the redis instance, both are in the same project. Any ideas? Thank you!

please read this docs section - https://docs.railway.app/guides/private-networking#ioredis you might not be directly using ioredis, but more than likely it's what beequeue is using under the hood

Hi @Brody 👋 I already tried that, still the same issue. Beequeue uses https://github.com/redis/node-redis.

does it use some very old version of that module? perhaps before it supported ipv6

jtourkosOP•2mo ago

If you check here https://github.com/redis/node-redis/blob/master/docs/client-configuration.md I also tried setting socket.family to 6

Brody•2mo ago

okay fair, are you getting these errors locally on when on Railway

jtourkosOP•2mo ago

The only difference is that when I try something like

const redisClient = createClient({
      url: appSettings.redisConnectionString,
      socket: {
        family: 6,
      },
    });

const redisClient = createClient({
      url: appSettings.redisConnectionString,
      socket: {
        family: 6,
      },
    });

i now get the same error but it tries to connect to localhost

Brody•2mo ago

that just means that's incorrect syntax and the client is falling back to it's default values for the host ?

jtourkosOP•2mo ago

on Railway after building while deploying

Brody•2mo ago

is redis in the same project?

jtourkosOP•2mo ago

yeah

Brody•2mo ago

are you pro?

jtourkosOP•2mo ago

yup

Brody•2mo ago

can you try switching to the v2 runtime in the service settings

jtourkosOP•2mo ago

where is that?

Brody•2mo ago

in the service settings

jtourkosOP•2mo ago

i don't see such a setting 🤔

Brody•2mo ago

https://docs.railway.app/overview/the-basics#service-settings

jtourkosOP•2mo ago

Yeah, i know where the service settings are, I just don't find something to switch to v2 🙂

Brody•2mo ago

oh my bad, sorry for assuming

jtourkosOP•2mo ago

no worries 🙂

Brody•2mo ago

let me get back to you when I'm at my computer, might end up needing a minimal reproducible example

jtourkosOP•2mo ago

Alright, thanks!

Brody•2mo ago

and I'll need a project id for that and unless it's super obvious, a service and environment name so I know I'm looking at the right stuff
