Now with the help of Certbot will generate wildcard certificate for our test domain erpnext.xyz
sudo certbot certonly --manual --preferred-challenges=dns --email nome@erpnext.xyz --server https://acme-v02.api.letsencrypt.org/directory --agree-tos -d *.erpnext.xyz
After executing the above command, the Certbot will share a text record to add to your DNS.
Please deploy a DNS TXT record under the name _acme-challenge.erpnext.xyz with the following value: J50GNXkhGmKCfn-0LQJcknVGtPEAQ_U_WajcLXgqWqo
Then you will receive:

If this doesn’t fix the issue you’re having, you’ve got something else wrong and bashing DO is not going to help anyone. If you want a managed server, look for hosting elsewhere. If you need help, ask someone or hire an admin that knows how to not only ‘set things up’ but knows how to secure your server as well. You’ll be glad you did. DO is not for novices, even if they have a lot of tutorials.
