echo -e nameserver 2a01:4f8:c2c:123f::1 > /etc/resolv.conf

2. Install acme.sh script by these command

curl https://get.acme.sh | sh -s [email protected] # Change this email for yours
source ~/.bashrc
bash ~/.acme.sh/acme.sh –upgrade –auto-upgrade

3. Confirm 80 port is not used, then run this command

bash ~/.acme.sh/acme.sh –issue -d ${domain} –standalone -k ec-256 –listen-v6 –insecure
