Rebuilding existing server

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. |, so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command: N/A

It produced this output: N/A

My web server is (include version):
nginx 1.14.0

The operating system my web server runs on is (include version):
Ubuntu 18.04

My hosting provider, if applicable, is:
Self hosting on Digital Ocean vps

I can login to a root shell on my machine (yes or no, or I don't know):

I'm using a control panel to manage my site (no, or provide the name and version of the control panel): no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):
certbot --version 1.25.0

Good day all.
For my existing server installation I used the following install command:
sudo apt-get remove certbot
sudo apt install snapd
sudo snap install core
sudo snap refresh core
sudo snap install --classic certbot
sudo ln -s /snap/bin/certbot /usr/bin/certbot
sudo certbot --nginx

My server is running fine ... no problem. I have to however do a major upgrade which may
render the server useless if the upgrade goes wrong. If I have to re-create the server from scratch
and want to use lets-encrypt again on the same domain, will the lets-encrypt allow me to register
again with a domain previously used for a server ?

It will be fine to reissue new certificates if you have to rebuild the server.

There are rate limits to prevent abuse, and in particular there’s a limit of 5 of the exact same certificate per week. If you rebuild your server multiple times it is possible you run into that.

You can read more read more about rate limits.


If you do not downgrade Certbot you can move the entire /etc/letsencrypt directory from one server to another without issue.

Just use the correct tool and options to that tool to keep the permissions and symbolic links intact.


Thank you @mcpherrinm , @9peppe , @Osiris for your prompt messages and indeed to take the
time to look at my concern.

It puts my mind at ease that it should not be a big problem to re-instate my certificates once my
servers are running again. I am currently busy with the upgrade of the servers and once that is
done, I shall attend to my certificates.

Much appreciated.
