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 ), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: wlbentley.com wlbentley.net
I ran this command: certbot --nginx
It produced this output:

You have an existing certificate that has exactly the same domains or certificate name you requested and isn't close to expiry.
(ref: /etc/letsencrypt/renewal/wlbentley.com.conf)
What would you like to do?
-------------------------------------------------------------------------------
1: Attempt to reinstall this existing certificate
2: Renew & replace the cert (limit ~5 per 7 days)

IMPORTANT NOTES:
- We were unable to install your certificate, however, we
successfully restored your server to its prior configuration.
- Congratulations! Your certificate and chain have been saved at:
/etc/letsencrypt/live/wlbentley.com/fullchain.pem
Your key file has been saved at:
/etc/letsencrypt/live/wlbentley.com/privkey.pem
Your cert will expire on 2018-10-12. To obtain a new or tweaked
version of this certificate in the future, simply run certbot again
with the "certonly" option. To non-interactively renew *all* of
your certificates, run "certbot renew"

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): No
=======
There was an existing Comodo/cloudflare certificate installed on the .com site, but I would like to switch all to Letsencrypt. Thx.
Hi,
Please try to remove the certificate from wlbentley.com:81 or simply run certbot certonly.
That’s just a duplicate certificate error in Nginx…
Thank you
Hi. Thanks for the fast reply.
Line 81 is just the first line after the server block that begins:
server {
# SSL configuration
#
listen 443 ssl http2;
listen [::]:443 ssl http2;
include snippets/ssl-wlbentley.com.conf;
include snippets/ssl-params.conf;
server_name wlbentley.com www.wlbentley.com;
I tried deleting the SSL server block in both .com and .net config files, but got the same message after certbot rebuilt the blocks.
So, not clear what you mean. How to remove the certificate?
(The certificates are new, so ‘certonly’ yields ‘no action taken’.)
Can you clarify how to remove the previous certificate?

Could you show the full parsed nginx configuration?
nginx -T
It sounds like Certbot is struggling to understand what to do with your particular config when attempting installation of the certificate.

Perhaps it’s a bad nginx config?

When you use --nginx, Certbot configures these two things for you.
I think what's happening is that Certbot fails to understand these includes, and ends up introducing erroneous duplicates.
You should be able to comment your SSL includes out, run certbot --nginx again, and Certbot should be able to apply its own SSL includes successfully.
Ok. Certbot --nginx ran without error this time.
the .net site uses the letsencrypt certificate, but the .com site is still using the old Comodo certificate.
They’re both secure, which is good, but I’d rather resolve this and have the certificates in sync, rather than wait until the Comodo cert expires in January.
Any more ideas on how to remove the Comodo cert?

That domain is sitting behind Cloudflare's proxy/CDN. Unless you get rid of the proxy, then the Comodo certificate will be what's presented to the browser. No way around it.
Ah…
That doesn’t ring any bells at all. I’ll have to dig deeper to see how I set that up.
Thanks for all your help.
So… when it’s removed from the Cloudflare CDN, the letsencrypt certificate will be there waiting, right?
_az
July 15, 2018, 2:46am

Well, what will happen is that browers will connect directly to your server instead of to Cloudflare.
As a result, they will see the certificate from your server (the Let's Encrypt one) rather than the certificate from Cloudflare (the Comodo one).
Got it. I figured out how that happened.
Thanks again.
