Why my ftp server doesnt work in passive mode but works in active mode?

Question

Trying to setup a FTP server on a EC2. I have installed vsftp and followed this tutorial

When I try to connect with the -p option I cannot pass any command. Everything is smooth without it.

I have setup vsftpd.conf:

allow_writeable_chroot=YES
pasv_address=<my-ip>
pasv_enable=Yes
pasv_min_port=50000
pasv_max_port=51000
port_enable=YES

And opened the port (20-21 && 50000-51000 using Terraform here)

resource "aws_security_group" "ftp_passive_port" {
  name = "ftp_passive_port"
description = "Access to FTP passive"
  vpc_id      = aws_vpc.din_vpc.id
ingress {
    from_port   = 50000
    to_port     = 51000
    protocol    = "tcp"
    cidr_blocks = [...]
  }
Allow all outbound traffic.
egress {
    from_port   = 0
    to_port     = 0
    protocol    = "-1"
    cidr_blocks = ["0.0.0.0/0"]
  }
}

I got this error :
