docker.io read udp connection refused

Recently I faced problem while setup docker compose application

ERROR: Get https://registry-1.docker.io/v2/: dial tcp: lookup registry-1.docker.io on [::1]:53: read udp [::1]:57728->[::1]:53: read: connection refused

after short internet reading I discovered that it is connected with DNS query problems that are generated from my machine to ISP DNS server.

To avoid that kind of problems in future just redirected all my DNS traffic to the Google DNS instead of local ISP.

For doing it just need to edit resolv.conf file in Your Debian based machine:

Step 1

vi /etc/resolv.conf

Step 2
Insert following lines if the file is empty or edit appropriate

nameserver 8.8.8.8
nameserver 8.8.4.4

After changing the DNS problem solves.
