I want to add my NTP server. But I can't


I want to join in NTP Pool But I can’t.

I saw this message.

You can see my static IP.

OS : Ubuntu 20.04 LTS Server

I opened ufw allow 123/udp.

And I followed recommended configuration in NTPPool Project.

Help Me. Please.

And Thank you for spare your time.

traceroute reaches and stops.

Perhaps Korea University, who owns the IP address, blocks NTP (UDP port 123)

Simple check reveils all.

Your port seems to be blocked.

Looks like it’s working now and he was able to join the pool :slight_smile:
