Neither renewal nor issue works: acme.sh on debian8

Hello,
i was able to get a certificate via acme.sh once. Since then, the (automatic via cron) renewal failed as well as my manual attempts to renew or re-issue a certificate failed. I am stuck an need some help.

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: www.naturundtext.de

I ran this command: ./acme.sh --renew-all --debug --log
and:./acme.sh --issue -d www.naturundtext.de -d www.basilisken-presse.de -d www.herpetoshop.de --webroot /var/www/live --apache --force --debug

It produced this output:

Hello @merlyn12345

Your acme.sh install defaults to use another certificate authority's ACME API, namely, ZeroSSL. Although it doesn't immediately look like your issues are an ACME API problem, you will be able to get the best help regarding ZeroSSL's ACME API from their support team.

If you would like to switch the ACME API your acme.sh uses you do so by adding:
--server letsencrypt to your command, documented here. Since Let's Encrypt has rate-limits you should also review how to set acme.sh to use the Let's Encrypt Staging environment while you work to fix your client and/or webserver.

Right now, it looks like you might be missing packages that acme.sh uses either for debug or for the issuance logic.

Try running which socat to confirm it's installed.

Welcome to the Let's Encrypt Community, Georg :slightly_smiling_face:

To expand further upon what @jillian has already correctly stated, your previous certificate issued on 2021-05-07 was a Let's Encrypt certificate, not a ZeroSSL certificate. If you use a renewal command rather than a new certificate command, acme.sh should remember that your previous certificate was from Let's Encrypt and try to renew it from Let's Encrypt. Neither that renewal command nor the new certificate command you are using are good though since both commands only acquire a certificate covering the www subdomain names of each of your three domain names. Your certificate should also cover the base (apex) domain names themselves as well as the www subdomain names for a total of six domain names on your certificate.

Hello jillian,

thanks a lot for your fast answer. Using --server letsencrypt did not change anything, maybe because the certificate i tried to renew was already issued in may.

You are right, there is no socat installed on my debian box. I kind of inherited this very outdated system and was untill now not allowed to update, because it would break the configuration of the shop installed.

I have also not been able to install socat via apt, there seem to be a lot of dependencies missing. I was hoping to be able to use acme.sh for renewal anyway, as i was able to get a certificate directly after i installed it in may.

So, i will try to get socat installed on my box, but i do not have al lot of faith...

There is also some strange behaviour exposed by the webserver after acme.sh has completed: any request for files in /.well-known/acme-challenge/ are answered with an 404 error. After restarting the webserver, a request to that directory resoves fine. Is that an intended behaviour?

Cheers, Georg
