acme-companion Certificates not renewed when using custom ACME Endpoint

Bug description

For my internal network (where I cannot get letsencrypt certificates) I've set up a step-ca server exposing an ACME endpoint. This works flawlessly, until the certificates expire and the companion would need to refresh them. This does not happen automatically and I need to run the force_renew script manually (which works 100% of the time).

Maybe I am missing some parameter, but could not find anything in the docs. Looking for advice on how I'll be able to automate the cert refreshing.

Thanks!

Just today I had trouble renewing the certificate as well. Unfortunately, I run the acme-companion update every day, so I exceeded the maximum number of new requests, I have to wait for the log week.

Aug 30 '21 21:08 hufhend

@steilerDev is the renewal date given by acme.sh in the acme-companion logs correct or not ?

@hufhend this issue is about using acme-companion with a custom ACME CA, not with Let's Encrypt.

Aug 31 '21 09:08 buchdag

Where/When would the date be printed in the logs?

Aug 31 '21 17:08 steilerDev

Those lines in the nginxproxy/acme-companion container logs:

[Sat Aug 14 14:34:00 UTC 2021] Skip, Next renewal time is: Fri Sep 24 20:41:17 UTC 2021

Sep 30 '21 16:09 buchdag

@buchdag in that case: no the date reflected in the log is not correct (one example, but this is true for all domains):

Creating/renewal paperless.steilergroup.net certificates... (paperless.steilergroup.net)
[Fri Oct  1 08:44:33 UTC 2021] Domains not changed.
[Fri Oct  1 08:44:33 UTC 2021] Skip, Next renewal time is: Wed Nov 24 06:00:12 UTC 2021
[Fri Oct  1 08:44:33 UTC 2021] Add '--force' to force to renew.

Screenshot 2021-10-01 at 11 05 55

As you see I set the default and max cert duration to 720hrs and it seems that the acme-companion is always a month off.

Oct 01 '21 09:10 steilerDev

Running /app/cert_status gives me the following output, seeming to read the cert correctly but somehow telling me that the fullchain is expired....

/etc/nginx/certs/paperless.steilergroup.net/fullchain.pem: EXPIRED
Certificate was issued by steilerGroup-CA-v3 Intermediate CA
Certificate was valid until Oct 25 06:00:09 2021 GMT
Subject Name:
- paperless.steilergroup.net
Certificate is used by the following domain(s):
- paperless.steilergroup.net

Oct 01 '21 09:10 steilerDev

I'm starting to suspect that the default acme.sh minimum validity before renewal isn't properly handling certificate issued with a validity < 1 month. Could you try issuing certificates with a validity of let's say 840 hours (35 days) ?

We used to have environment variables to configure this but I had to ditch this feature when moving to acme.sh, if this is what is causing your issue I'll look into adapting it to acme.sh.

Oct 01 '21 09:10 buchdag

Changing it to 840 hours gave me the following:

Cert is valid until 7. November 2021 at 09:01:40 Central European Standard Time
Logs show Skip, Next renewal time is: Thu Dec 2 08:01:34 UTC 2021

Then I adjusted the time to 90 days (2160 hours), in order to match the default behaviour of letsencrypt:

Cert is valid until 1. January 2022 at 09:10:22 Central European Standard Time
Logs show Skip, Next renewal time is: Thu Dec 2 08:10:25 UTC 2021

This still does not match, is this expected? Otherwise I will only be able to report back in 3 months time

Oct 03 '21 08:10 steilerDev

Hey all, Are there any news regarding this? I think I ran into the same issue and can't figure out why the certificates are not renewed :-( Or are there any ideas how to fix or workaround this? Thanks in advance!

Dec 16 '22 08:12 chspnk

It looks like acme.sh just defaults to a renewal period of 60 days. This matches the timestamps I'm seeing where the "Skip, Next renewal time" is 60 days out. It also appears to match @steilerDev's logs as well.

I think adding an environment variable back to configure the "--days" argument of acme.sh will allow us to resolve this issue.

Mar 14 '23 04:03 sushifor1

It looks like someone already made the changes necessary to support the --days parameter for acme.sh and submitted PR #896 and is pending review.

@buchdag Let me know if I can help move this along in any way.
