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

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.

Answer 1

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.

Answer 2

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
});
