Redis ERR Command not allowed

The command is disabled in the current configuration (e.g., protected mode).

When encountering the error "ERR Command not allowed from Redis," the user should:

  1. Verify the command being executed to ensure it is correctly formatted and is a valid command for the version of Redis in use.
  2. Check if the command is being blocked by Redis security settings, such as rename-command in the Redis configuration file, which could have renamed or disabled the command for security purposes.
  3. If using Redis in a managed environment (like AWS ElastiCache or Azure Cache for Redis), check if the command is restricted by the provider.
  4. Execute the INFO command to gather information about the server and its configuration, which can help identify misconfigurations or restrictions. Specifically, look into the # Security section for any command renaming or disabling:

INFO

  1. Review the Redis logs for any warnings or errors related to command execution or security policies that might have led to this error. If you have access to the file system where Redis stores logs, locate the log file (usually named redis-server.log) and search for relevant entries.
  2. If Redis Sentinel is in use and the command was issued to a replica, ensure that the command is read-only, as replicas by default do not accept write commands. If necessary, connect to the master node to execute write commands.

Take action based on the findings from these investigations to resolve the issue.
