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. crt.sh | 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: cider4u.uk
I ran this command: certbot
It produced this output: No certificate found
My web server is (include version): Nginx
The operating system my web server runs on is (include version): Ubuntu 24.04.1 LTS
My hosting provider, if applicable, is: N/A
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?!
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): 2.9.0
Other info:
In the letsencrypt folder I have "accounts", "cli.api", "renewal" and "renewal-hooks". In the "accounts" folder I have an "acme-vo2.api.letencrypt.org" folder with a "directory" containing what looks like a key.
(I had not installed acme, installed it out of desperation! but no change)
I have nothing in "renewal", "deploy", "post" and "pre" folders:
root@cider4u:/etc/letsencrypt# ls
accounts cli.ini renewal renewal-hooks
root@cider4u:/etc/letsencrypt# cd accounts
root@cider4u:/etc/letsencrypt/accounts# ls
acme-v02.api.letsencrypt.org
root@cider4u:/etc/letsencrypt/accounts# cd ..
root@cider4u:/etc/letsencrypt# cd renewal
root@cider4u:/etc/letsencrypt/renewal# ls
root@cider4u:/etc/letsencrypt/renewal# cd ..
root@cider4u:/etc/letsencrypt# cd renewal-hooks
root@cider4u:/etc/letsencrypt/renewal-hooks# ls
deploy post pre
root@cider4u:/etc/letsencrypt/renewal-hooks# cd deploy
root@cider4u:/etc/letsencrypt/renewal-hooks/deploy# ls
root@cider4u:/etc/letsencrypt/renewal-hooks/deploy# cd ..
root@cider4u:/etc/letsencrypt/renewal-hooks# cd post
root@cider4u:/etc/letsencrypt/renewal-hooks/post# ls
root@cider4u:/etc/letsencrypt/renewal-hooks/post# cd ..
root@cider4u:/etc/letsencrypt/renewal-hooks# cd pre
root@cider4u:/etc/letsencrypt/renewal-hooks/pre# ls
root@cider4u:/etc/letsencrypt/renewal-hooks/pre#
I do not remember installing/running acme but read a little and something may have changed recently. I have previously run certbot to renew without problems.
FYI I have little knowledge certificates but have been using linux for over 20 yrs and can use the cli reasonably well and ssh into my server which still shows the cert and the same expiry date in 2 weeks time.
I can see there are tools I could use to diagnoes further but would like some advice in case the above information is sufficient.
PS I am 80 years old so please be gentle!
Thanks for your time
