      username: process.env.REDIS_USER,
      family: 0,
      retryStrategy: (times) => {
        // reconnect after
        return Math.min(times * 50, 2000);
      },
    };

13314144-b328-475d-867f-a0337164519f I have set the family as you can see i also have sleep 3 in my start command

Brody•9mo ago

nixpacks or dockerfile?

TurboFarmer9000OP•9mo ago

nixpacks with the sleep command in the package.json start command

Brody•9mo ago

according to the redis service settings, is that host correct?

TurboFarmer9000OP•9mo ago

redis-cache-staging.railway.internal Should i have the http infront ?

Brody•9mo ago

redis does not use http

TurboFarmer9000OP•9mo ago

kkk let me check. should i justhave redis-cache-staging.railway.internal

Brody•9mo ago

is the redis database in the same environment as the service thats trying to connect to it

TurboFarmer9000OP•9mo ago

yes

Brody•9mo ago

are you sure the sleep 3 is being ran?

TurboFarmer9000OP•9mo ago

yes

Brody•9mo ago

how so?

i have removed http:// and redeploying now to check [ioredis] Unhandled error event: Error: connect ECONNREFUSED 127.0.0.1:6379 at node_internal_captureLargerStackTrace (node:internal/errors:496:5) at node_internal_exceptionWithHostPort (node:internal/errors:671:12) at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1555:16)

Host is set correctly in the variables

Brody•9mo ago

you are still using shared variables

Solution

Brody•9mo ago

please see this for ioredis https://docs.railway.app/guides/private-networking#known-configuration-requirements-for-ipv6

TurboFarmer9000OP•9mo ago

i have applied everything from the railway docs

Brody•9mo ago

please stop using shared variables for this use reference variables

TurboFarmer9000OP•9mo ago

ok changed from shared variables, using reference vars from redis service

TurboFarmer9000OP•9mo ago

Redis port has gone blank on the redis service

Brody•9mo ago

use the private url variable please just like the example in the docs shows

TurboFarmer9000OP•9mo ago

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

Brody•9mo ago

probably just configured it wrong

TurboFarmer9000OP•9mo ago

@Brody thanks for all the help man. appreciate it

Brody•9mo ago

no problem

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.

No worries, the links are indeed missing.Getting ioredis setup correctly with private networking checklist -Make sure you have the V2 runtime enabled in your service settings.Use the URL syntax for the ioredis client as shown here - https://github.com/redis/ioredis/blob/main/README.md#connect-to-redisUse environment variables.Append ?family=0 to the end of the URL.Example -const redis = new Redis(process.env.REDIS_URL + "?family=0");
