How to Fix an "AUTH failed" Error When Connecting to Valkey?

If you encounter the following error when connecting to your Vultr Managed Valkey Database:

AUTH failed: WRONGPASS invalid username-password pair or user is disabled.

It indicates an issue with your authentication credentials or connection method. This error can occur due to an incorrect password, wrong username, using a non-TLS connection, or if the database is not fully operational. To resolve the issue:

• Use the correct connection string: Copy the connection string directly from the Vultr Customer Portal. Valkey requires a secure URI format for connections. It should look like:

  rediss://<username>:<password>@<hostname>:<port>

  Important

  rediss:// indicates a TLS-encrypted connection. Non-TLS URIs (redis://) will fail authentication.

• Connect using redis-cli: Provide the full URI with the -u flag:

  console Copy

  $ redis-cli -u rediss://<username>:<password>@<hostname>:<port>
  

  Explain Code

  This ensures the client uses the correct protocol, host, port, username, and password.

• Verify the database state: Ensure your Valkey database is Running and fully operational. Databases in states such as Rebalancing or Rebuilding will not accept connections and may produce authentication errors.
