Error: redis auth failed

Solution

Troubleshooting "Redis auth failed" Error

The "Redis auth failed" error occurs when Redis is unable to authenticate a client connection due to an incorrect password or authentication failure. Here are the steps to troubleshoot and resolve this error:

1. Check Redis Authentication Configuration

• Ensure that the Redis server is configured to use authentication.
• In the redis.conf file, verify that the requirepass directive is set to the correct password.

2. Verify Client Authentication

• Check the Redis client code to ensure that it is sending the correct password when connecting to the Redis server.
• Ensure that the password used by the client matches the one set in the Redis server configuration.

3. Restart Redis Server

• Try restarting the Redis server to see if the issue is resolved.
• Sometimes, a restart can clear any temporary authentication issues.

4. Check Redis Logs

• Examine the Redis logs for any error messages or clues that might help identify the root cause of the authentication failure.
• The logs are typically located in the /var/log/redis/ directory on Linux systems.

5. Verify Redis Server Permissions

• Ensure that the Redis server process has the necessary permissions to read the authentication password from the configuration file.
• Check the file permissions and ownership of the redis.conf file.

6. Test Authentication with redis-cli

• Use the redis-cli command-line tool to connect to the Redis server and test the authentication.
• Run redis-cli -a <password> to connect with the specified password.

By following these steps, you should be able to identify and resolve the "Redis auth failed" error in your Redis setup.
