[Python] Can not get remote access to RabbitMq server

I can't get remote access to the RabbitMq server. When I am doing this at one machine and connect to localhost:15672 it works, but when I try from a remote machine it's not.

I have already created a user with all permissions and check that 5672 port on computer works (just tried to connect to him from a remote computer). Also, I tried to connect to 15672 port, but no result.

credentials = pika.PlainCredentials(username= 'username', password='password')
parameters = pika.ConnectionParameters(host='188.19.100.226',
port=5672,
virtual_host= '/',
credentials=credentials)

connection = pika.BlockingConnection(parameters=parameters)
channel = connection.channel()

channel.queue_declare(queue='hello')

channel.basic_publish(exchange='',
routing_key='hello',
body=hello)
print ("Sent!")
connection.close()


I expect to see Sent!, but instead of I get:
