ioredis Unhandled error event: Error: connect ETIMEDOUT

Question

Has anyone encountered below error while connecting to standalone redis server using node js ioredis package?

Below is the error stack trace:

2018-08-16T10:52:18.351869060Z [ioredis] Unhandled error event: Error: connect ETIMEDOUT

2018-08-16T10:52:07.449403458Z at Socket.g (events.js:291:16)

This is occurring for instantiating only Standalone Redis object in node js. Below is the code I am using,

var publisher = new redis(redisPort, redisHost);

any solution would be highly appreciated.

You can probably try increasing the timeout limit since ioredis has a default timeout value.

Normally we would have it set as,

new Redis({
  connectTimeout: 10000
})

In your case, since you have,

var publisher = new redis(redisPort, redisHost);

You will have to edit your code to pass the connectTimeout parameter to be passed accordingly.

Hope this helps.

can you provide example for how to pass that param in my existing code line? – Ankur Soni Aug 16 '18 at 11:36
Sure, Can you please post the relevant code where you set the values for `redisPort` and `redisHost` variables respectively? – David R Aug 16 '18 at 12:06
Thx for this, ended hours of head banging against my wall! – Getter Jetter Jul 20 '19 at 14:27
@Oliver Krull, Glad it helped! :-) – David R Jul 20 '19 at 18:36
Default value for [connectTimeout](https://github.com/luin/ioredis/blob/master/API.md#new-redisport-host-options) is 10000 ms. – Rashidul Islam Aug 23 '21 at 18:22

It's a bit late but can be helpful in the future for somebody else.

const redis = new Redis({
   port: <your_redis_port>,
   host: <your_redis_hostname>,
   connectTimeout: 10000
});

I am using Redis client maintained by Heroku and for some strange reason the Redis credentials have been changed by Heroku, I have been facing the same issue until I double-check the old credentials and the one on Heroku and I realised they were no longer the same then copied the new one from Heroku and pasted it in my .env file and everything is working as expected now!!!

Yeah same thing happened to me. Weird. – TeemuK Jan 19 '22 at 14:02

If you happened to create the Redis client while you are initiating the project, this error would not occur as Heroku will automatically be updating the credentials for you. This error is a result of creating your project separately then later on you added the Redis client add-on. Hope my explanation is clear. By the way thanks for the upvote!! :)) – Shamxeed Jan 19 '22 at 16:53

Adding keepAlive helped me.

const redisClient = new Redis({
  host: CONFIG.REDIS_HOST,
  username: CONFIG.REDIS_USER,
  password: CONFIG.REDIS_PASSWORD,
  port: CONFIG.REDIS_PORT,
  lazyConnect: true,
  keepAlive: 1000,
});
