Last Updated: Dec 15, 2020

Problem description

When you use a Node client to connect to an apsaradb for Redis instance, the system prompts the error error:ready check failed:NOAUTH Authentication required. The following error message is returned:

Possible cause

The auth field specifies the connection address of the apsaradb for Redis instance. It must be the instance ID of the apsaradb for Redis instance. This problem is usually caused by authentication failure.

Solution

General certification failure needs to be checked from two aspects:

  • Check whether the password is correct.
  • Redis instance ID and password are required for user authentication. Therefore, you must check whether the format is correct.
    Note: you only need to use the connection password displayed in the Redis console.

Application scope

  • ApsaraDB for Redis
