Terkadang pada saat proses renewal Certs Letsencrypt sebuah domain muncul pesan error seperti dibawah :
Cert not yet due for renewal
All renewal attempts failed. The following certs could not be renewed:
/etc/letsencrypt/live/example.org/fullchain.pem (failure)
kemudian menyusul pesan error berikut :
Domain: example.org
Type: unauthorized
Detail: Invalid response from
https://example.org/.well-known/acme-challenge/Vr1t8IAE2lemQGW_KfkJO2P28xZMgLBkg8h93XkghpQ
[12.34.56.78]: "<html>\r\n<head><title>403
Forbidden</title></head>\r\n<body

To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address.
Mungkin secara logika dapat saja dibuatkan folder pada root domain sesuai dengan yang tertera diatas, tapi setelah aku coba ternyata tidak berhasil.
Untuk menyelesaikan itu cukup dengan menjalankan perintah (khusus yang menggunakan Nginx) berikut :
./letsencrypt-auto --nginx -d example.org
Apabila pesan yang muncul seperti dibawah, berarti proses telah berhasil dan Certs telah diperpanjang.

1: No redirect - Make no further changes to the webserver configuration.
2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you're confident your site works on HTTPS. You can undo this
change by editing your web server's configuration.

IMPORTANT NOTES:
- Congratulations! Your certificate and chain have been saved at:
/etc/letsencrypt/live/example.org/fullchain.pem
Your key file has been saved at:
/etc/letsencrypt/live/example.org/privkey.pem
Your cert will expire on 2020-02-07. To obtain a new or tweaked
version of this certificate in the future, simply run
letsencrypt-auto again with the "certonly" option. To
non-interactively renew *all* of your certificates, run
"letsencrypt-auto renew"
Cara diatas sudah aku coba pada Debian yang menggunakan web engine Nginx … metode diatas sukses.
Selamat mencoba ….
