[Python] ConnectionError: SERVER_CLOSED_CONNECTION_ERROR when connecting to multiple Redis...

I am trying to connect to multiple Redis hosts using Python's redis-py library. Here’s the code I am using:

import redis

self.redis_client = redis.Redis(
host=self.host,
port=int(self.port),
username=self.username,
password=self.password,
decode_responses=True
)
print(self.redis_client.ping())


This works perfectly for one of the hosts — I get a True response from ping().

However, for other hosts, I get the following error:

redis.exceptions.ConnectionError: Connection closed by server. (SERVER_CLOSED_CONNECTION_ERROR)
​

Interestingly, I am able to see data from all these hosts using the RedisInsight app, so the credentials and connectivity seem correct.

What I tried: Verified the host, port, username, and password (same as used in RedisInsight).

Why am I able to connect to one Redis host successfully, but getting SERVER_CLOSED_CONNECTION_ERROR for others?
