Error: redis auth failed

What's Causing This Error

The error message 'redis auth failed' typically occurs when the Redis instance is not configured with the correct authentication credentials or if the password provided is incorrect. Redis mandates authentication for clients to access its database, and this error message is generated if the authentication fails. Apart from this, network connectivity issues, firewall restrictions that block the Redis port (default port 6379), or permission issues that prevent Redis from reading the configuration file can also cause this error.

Solution - Here's How To Resolve It

To fix the 'redis auth failed' error, follow these steps:

  1. Ensure that the authentication credentials used to connect to Redis are correct. Check the Redis configuration file for the password, or reset it if necessary.
  2. Verify that your Redis instance is running and there are no network connectivity problems between the client and server. Try pinging the Redis server to verify its reachability.
  3. Check for any firewall restrictions that may be blocking the Redis port. Temporarily disable the firewall to see if this resolves the issue.
  4. Confirm that Redis has permission to read the configuration file. Check file permissions and ownership to ensure that Redis can access and read the file.

By taking these measures, you should be able to diagnose and resolve the 'redis auth failed' error. If you encounter persistent issues, consult the Redis documentation or seek assistance from a Redis expert.
