Failed to renew expired certificate


#2

Hi @Reynaldo,

The crt.sh log that you linked to shows that you’ve successfully renewed your certificate six times in the last four days, including once today (!). (In that log, dates are calculated based on the UTC time zone.)

Do you not have access to the newly-issued certificates that resulted from all of these successful renewals?


#3

Ah I see, but then they are not being saved. And the certbot tool complains of rate limit.

Attempting to renew cert (siminchikkunarayku.pe) from /etc/letsencrypt/renewal/siminchikkunarayku.pe.conf produced an unexpected error: urn:acme:error:rateLimited :: There were too many requests of a given type :: Error creating new cert :: too many certificates already issued for exact set of domains: siminchikkunarayku.pe: see https://letsencrypt.org/docs/rate-limits/. Skipping.
All renewal attempts failed. The following certs could not be renewed:
/etc/letsencrypt/live/siminchikkunarayku.pe/fullchain.pem (failure)


#4

Are you sure they’re not being saved?

Could you paste the output of these commands?

There really isn’t a /etc/letsencrypt/archive/siminchikkunarayku.pe/ directory?


#10

No, only siminchikkunarayku.pe-0001


#11

Well… It’s just a matter of fixing what’s happened to Certbot’s configuration files.

Do you want to do it today? It might be a little simpler to wait until January 23 or so when you can just issue a new certificate (though you’d have to stop it from repeating what it’s doing now first).


#12

Yes, if possible, this has been not working for some days already.


#13

Yeah.

Please post:

sudo ls -lt /etc/letsencrypt/keys/

Note: It’s a directory full of private keys. Don’t give people your private key files! But a list of filenames isn’t very sensitive.

Okay…

/etc/letsencrypt/keys/ contains your private keys, and all Let’s Encrypt certificates are in public logs As long as the keys aren’t lost, you can download the certificates, fix the files, and put everything back together again.

Going by the timestamps, this key:

is for this certificate:

https://crt.sh/?id=306294887

Let’s see…

Go to your home directory or something, then:

mkdir -m 755 siminchikkunarayku.pe
cd siminchikkunarayku.pe

Download the certificate:

curl -o cert1.pem https://crt.sh/?d=306294887

and the intermediate:

curl -o chain1.pem https://letsencrypt.org/certs/lets-encrypt-x3-cross-signed.pem.txt

and create the “fullchain” file:

cat cert1.pem chain1.pem >fullchain1.pem

and copy the private key (as root):

sudo cp -ai /etc/letsencrypt/keys/0094_key-certbot.pem privkey1.pem

You should be able to double check the private key and certificate match like this:

openssl x509 -modulus -noout -in cert1.pem | sha256sum
sudo openssl rsa -modulus -noout -in privkey1.pem | sha256sum

If the hashes are the same, they match.

Make sure the permissions on the other files are reasonable:

chmod 644 cert1.pem chain1.pem fullchain1.pem

Make sure the directory and files are owned by root:

sudo chown root:root cert1.pem chain1.pem fullchain1.pem
cd ..
sudo chown root:root siminchikkunarayku.pe

Move it to /etc/letsencrypt/archive:

sudo mv -i siminchikkunarayku.pe /etc/letsencrypt/archive/

And fix the symlinks in the /etc/letsencrypt/live directory:

sudo ln -fs ../../archive/siminchikkunarayku.pe/cert1.pem /etc/letsencrypt/live/siminchikkunarayku.pe/cert.pem
sudo ln -fs ../../archive/siminchikkunarayku.pe/chain1.pem /etc/letsencrypt/live/siminchikkunarayku.pe/chain.pem
sudo ln -fs ../../archive/siminchikkunarayku.pe/fullchain1.pem /etc/letsencrypt/live/siminchikkunarayku.pe/fullchain.pem
sudo ln -fs ../../archive/siminchikkunarayku.pe/privkey1.pem /etc/letsencrypt/live/siminchikkunarayku.pe/privkey.pem

If I got that right, everything should be okay now. And Certbot should renew correctly in about 59 days.


#16

it went all smooth, thanks!

Can I continue using ubuntu repo’s certbot?
I had downloaded certbot-auto and try it once too.

A cron job is still needed for auto renewal?


#17

That’s hard to say… :confused:

As things are now, you’re using Certbot 0.19.0 and TLS-SNI-01 validation. Renewal will eventually stop working.

If the PPA is upgraded to Certbot 0.21.0 in the next couple months, you won’t have to switch to certbot-auto.

That probably didn’t do any harm, but you could examine /etc/letsencrypt/renewal/siminchikkunarayku.pe.conf to check if it was created with 0.19.0 or 0.21.0.

The Certbot PPA package includes a systemd timer to automatically renew.

If you use certbot-auto, you need to deactivate the certbot package’s timer (by uninstalling the package, or disabling the timer with systemctl), and set up a timer or cron job to run certbot-auto renew.


#18

renew_before_expiry = 30 days

version = 0.17.0
archive_dir = /etc/letsencrypt/archive/siminchikkunarayku.pe
cert = /etc/letsencrypt/live/siminchikkunarayku.pe/cert.pem
privkey = /etc/letsencrypt/live/siminchikkunarayku.pe/privkey.pem
chain = /etc/letsencrypt/live/siminchikkunarayku.pe/chain.pem
fullchain = /etc/letsencrypt/live/siminchikkunarayku.pe/fullchain.pem

Options used in the renewal process

[renewalparams]
authenticator = apache
installer = apache
account = ae6c152b0093048b4482f3323a5937a5


#19

Can I touch this file manually , or can the tool update this?


#20

You probably don’t need to make any manual changes to it.
