Problem with expired cert

Help
1

My domain is:inwtx.net

I ran this command:./certbot-auto

It produced this output:said everything ok

My web server is (include version):Nginx version: nginx/1.6.2

The operating system my web server runs on is (include version):Linux 9.0

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:Putty

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot):certbot 0.37.2

I am getting an error saying that 1 of 3 certs is expired. Some are not able to get to my server (mail, I think). Here is a rundown, Thanks:

Hi @ranch

checking your domain there are older certificates ( https://check-your-website.server-daten.de/?q=inwtx.net#ct-logs ):

Issuer not before not after Domain names LE-Duplicate next LE
Let's Encrypt Authority X3 2019-08-23 2019-11-21 inwtx.net
1 entries duplicate nr. 1
Let's Encrypt Authority X3 2019-07-21 2019-10-19 inwtx.net, www.inwtx.net

Let's Encrypt Authority X3 2019-05-20 2019-08-18 www.inwtx.net

Let's Encrypt Authority X3 2019-04-22 2019-07-21 inwtx.net, mail.inwtx.net, www.inwtx.net
3 entries

But the certificate with three domain names isn't renewed.

Looks like your mailserver uses the wrong - expired - certificate.

Checking your subdomain nothing is visible - https://check-your-website.server-daten.de/?q=mail.inwtx.net - no https subdomain, no mail port. And only the same - expired - certificate via CT-log.

Looks like you had a correct certificate. Then the renew didn't work. Now it's expired.

What says

./certbot-auto certificates

Thanks for replying, I don’t know too much about certs. Here is what I think you are requesting:

root@inwtx~# ./certbot-auto certificates
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Invalid OCSP response status for /etc/letsencrypt/live/inwtx.net/cert.pem: OCSPResponseStatus.UNAUTHORIZED

There you see the problem. There is no active certificate with three domain names.

So create a new certificate with the three domains inwtx.net mail.inwtx.net www.inwtx.net.

Then change your mail server, so this certificate is used.

Thanks, I’ll do that. I guess I really only needed one cert for inwtx.net, since the www and mail are pointing to inwtx.net in the sites DNS record.

If the domain name mail.inwtx.net is used, you need a certificate with that domain name. Same with your www version. The ip address isn't relevant.

Thanks. I renewed and got a strange message concerning the mail.inwtx.net renew, but upon testing it with a program that was choking on the expired cert found that it is getting through now.

Thanks again for your help.

Now you have a new certificate

Issuer not before not after Domain names LE-Duplicate next LE
Let’s Encrypt Authority X3 2019-08-23 2019-11-21 inwtx.net, mail.inwtx.net, www.inwtx.net - 3 entries duplicate nr. 1

But your port 443 and your mail ports are invisible, so it’s impossible to check if you use that certificate.
