You probably have the port closed in the firewall

ufw allow 9987/udp

Try this as root.

Failing that try firewall-cmd --zone=public --add-port=9987/udp

If you don’t have ufw of firewalld on the system then you need to find the equivalent command for “iptables” to open the port.

done it with:

iptables -A INPUT -p udp --dport 9987 -j ACCEPT

but i still get:
