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. [https://crt.sh/?q=example.com](https://crt.sh/?q=example.com)), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: dolomitisistemas.com.br

I ran this command: certbot certonly --manual -d www.dolomitisistemas.com.br

It produced this output:  
IMPORTANT NOTES:

- Congratulations! Your certificate and chain have been saved at:  
/etc/letsencrypt/live/dolomitisistemas.com.br/fullchain.pem  
Your key file has been saved at:  
/etc/letsencrypt/live/dolomitisistemas.com.br/privkey.pem  
Your cert will expire on 2020-01-20. To obtain a new or tweaked  
version of this certificate in the future, simply run certbot  
again. To non-interactively renew _all_ of your certificates, run  
“certbot renew”

- Your account credentials have been saved in your Certbot  
configuration directory at /etc/letsencrypt. You should make a  
secure backup of this folder now. This configuration directory will  
also contain certificates and private keys obtained by Certbot so  
making regular backups of this folder is ideal.

- If you like Certbot, please consider supporting our work by:

My web server is (include version):

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

My hosting provider, if applicable, is:

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

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

The version of my client is (e.g. output of `certbot --version` or `certbot-auto --version` if you’re using Certbot): certbot 0.37.1

Hello, I’m new to certbot. I’ve installed Certbot via Homebrew on my Mac and then I ran sudo certbot certonly --manual -d www.dolomitisistemas.com.br . It generated the files in the folder… the fullchain.pem is ok, but the privkey.pem is blank!

I’ve already tried to uninstall the brew plugin and install it again, but the same problem occoured.

Can someone help me? Thanks in advance.
