Your system denies to send packages over UDP.

Port is not opened
or firewall blocks traffic
or open for wrong IP
or package is send from wrong IP
or IP you set in server does not exist on the machine.

There is a ton of reports and solutions that can be found.

I have the server more then 10 years
I didn’t close ports and I checked again. open (2008, 2010, 30033, 10011, 41144)
firewall blocks traffic or how can i know what specific i blocking a lot of ddos IPs (route) thanks to your lovely webserver list that not hides IPs…
