DENIED Redis is running in protected mode because protected mode is enabled

DENIED Redis is running in protected mode because protected mode is enabled,
 no bind address was specified, no authentication password is requested to clients.
 In this mode connections are only accepted from the loopback interface. 
If you want to connect from external computers to Redis you may adopt one of 
the following solutions: 1) Just disable protected mode sending the command
 'CONFIG SET protected-mode no' from the loopback interface by connecting to
 Redis from the same host the server is running, however MAKE SURE Redis is not 
publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change
 2) Alternatively you can just disable the protected mode by editing the 
Redis configuration file, and setting the protected mode option to 'no', 
and then restarting the server. 3) If you started the server manually just 
for testing, restart it with the '--protected-mode no' option. 4) Setup a bind 
address or an authentication password. NOTE: You only need to do one of the above 
things in order for the server to start accepting connections from the outside.

To solve the process

I tried to restart redis, replace redis with a new jar package, and turn off redis protection mode, which did not help. Later, I found the reason for the error. I happened to see that Unexpected end of stream was connected to redis by a process.

It seems that I can only change this value once I have access to the redis cluster.
