Yes you are right i tried to generate a Let's Encrypt certificate using the lego tool but i cant generate because of did it before for another instance and mistakenly i deleted that instance. I created new ec2 instance with bitnami wordpress and i want to generate ssl certificate for it with same domain name i used before but it gives me error..
this is what i tried
bitnami@ip-172-31-41-21:/tmp$ sudo lego --email="firstname.lastname@example.org" --dom ains="*.nextbigthings.info" --domains="www.nextbigthings.info" --path="/etc/lego " run
and it gave me this
2018/10/08 01:00:54 No key found for account email@example.com. Generatin g a curve P384 EC key.

Your account credentials have been saved in your Let's Encrypt
configuration directory at "/etc/lego/accounts/acme-v02.api.lets email@example.com".
You should make a secure backup of this folder now. This
configuration directory will also contain certificates and
private keys obtained from Let's Encrypt so making regular
backups of this folder is ideal.
