OperationalError [WinError 10061] No connection could be made because the target machine actively refused it

I'm trying to send a message to a newly registered user in Django using Redis.

I had a project with the analogical functionality and it worked.

In my current project, I get this error "OperationalError [WinError 10061] No connection could be made because the target machine actively refused it."

I noticed that in that other similar project I had had colorful text of Celery instance's methods (config_from_object and autodiscover_tasks) in VS Code and in the new project they weren't colorful, just a simple text. I thought maybe it was the problem I checked the interpreter and realized it wasn't the one that's in the .venv folder, so I changed it to the .venv interpreter.

app.config_from_object("django.conf:settings")
app.autodiscover_tasks()

The text of the methods became colorful but it didn't solve anything.

I have Docker, Django server and celery run.

I'm using Docker with Redis, I forwared ports when creating the container.

The container is run.

Host is set to 127.0.0.1 in settings.py

settings.py:

EMAIL_HOST = "smtp.gmail.com"
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = "<email>"
EMAIL_HOST_PASSWORD = "<password>"

REDIS_HOST = "127.0.0.1"
REDIS_PORT = "6379"
BROKER_URL = "redis://" + REDIS_HOST + ":" + REDIS_PORT + "/0"
BROKER_TRANSPORT_OPTIONS = {"visibility_timeout": 3600}
CELERY_RESULT_BACKEND = "redis://" + REDIS_HOST + ":" + REDIS_PORT + "/0"

celery.py:

import os

from celery import Celery

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "shop.settings")

app = Celery("shop", 
             broker_connection_retry=False,
             broker_connection_retry_on_startup=True)

app.config_from_object("django.conf:settings")
app.autodiscover_tasks()

I also ran these commands:
Test-NetConnection -ComputerName 127.0.0.1 -Port 6379
docker ps --format "table {{.Names}}\t{{.Ports}}\t{{.Status}}"

ComputerName : 127.0.0.1

RemoteAddress : 127.0.0.1

RemotePort : 6379

InterfaceAlias : Loopback Pseudo-Interface 1

SourceAddress : 127.0.0.1

TcpTestSucceeded : True

docker ps --format "table {{.Names}} \t{{.Ports}} \t{{.Status}}"

NAMES PORTS STATUS

my-redis 0.0.0.0:6379->6379/tcp Up 5 hours

Nothing helped. What else can be the problem?

Thank you for answers in advance
