redis failed to create socket

Faced a problem with redis connection. Host and port configured, redis container in docker worked fine and I have no idea why this exception occured.

How I run this test:

run docker container with redis -> get into redis cli and do "redis-server"

cli screenshot:

after what I run a test.

P.S. redis worked fine in console

redis console:

test

@SpringBootTest
class MessengerApplicationTests {

    @Test
    void contextLoads() {
        Jedis jedis = new Jedis();

        System.out.println(jedis.keys("*"));
    }

}

exception

I was using wrong port because I had an enterprise edition which had three different ports
