Is there a simple free ddns?

Question

linux

Good afternoon!
Given: A
small server with a dynamic white IP running pure Ubuntu
Task:
Connect from the outside by dns name at no extra cost
Attempted solution:
Created an account on freedns.afraid.org
Installed ddclient and configured ddclient.conf

# Configuration file for ddclient generated by debconf
#
# /etc/ddclient.conf

protocol=dyndns1
use=if, if=ppp0
server=freedns.afraid.org
login=mylogin
password='mypassword'
myserver.mooo.com

There is swearing in the logs and, accordingly, the dns record is not updated

Google said that this is an ancient bug that no one will fix.
Please suggest a reasonable alternative.
