How to setup tftpd-hpa?

Question

linux

Good day!
Kali distribution (not my choice).
Installed tftp server (tftpd-hpa). In the configuration file (/etc/default/tftpd-hpa) I made the following settings:

TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/tftp"
TFTP_ADDRESS="0.0.0.0:69"
TFTP_OPTIONS="--ipv4 --secure --create --umask 027 --permissive"

After rebooting the service and checking its status (everything is OK), I check the availability of the port:
nc -uv 1.1.1.2 69 - Everything is fine, the port is open
nmap -sU -p U:69 1.1.1.2 - The port is closed

When copying the file to the tftp server with cisco, I get Timed out attempting to connect
