ReplyError: NOAUTH Authentication required - even if password 100% correct.

Hello colleges.

I have issue with authenticated connection to Redis. I set up password in redis.conf and in redis-cli authentication is passing normally, but in ioredis client not. It always throw error: ReplyError: NOAUTH Authentication required - even if password is 100% correct. Password is simple for testing of course. Without setting password everything also is OK.

My code:

const Redis = require('ioredis')

const client = new Redis({
   host: '127.0.0.1',
   port: 6379,
   db: 0,
   password: 'qwerty',
   enableReadyCheck: true,
   autoResubscribe: true,
   retryStrategy: times => {
      return Math.min(times * 500, 5000)
   }
})

client.on('ready', () => {
   console.log('Redis server is ready.')
})

client.on('error', error => {
   console.log('Error in Redis server: ' + error)
})

What could be the problem? Thank you.

Just leaving this here for future persons.

This issue will likely happen if you set a password for Redis while you have an instance already running. So if you’re sure that your password is correct, restart the Redis server brew services stop redis and brew services start Redis. You should not have the issue again.

yeah it seems there’re three Redis instance being created (can tell from the first three lines in the logs), two of which don’t have password option set.

Thank you so much for Your help. Problem is not in ioredis at all. I am using BullMQ with Redis, so BullMQ probably is creating multiple instances of connection or any other problem.

Thank you.
