Wildcard certificate is considered invalid by Google Chrome

My domain is:
sdxlive.com

in /etc/nginx/:sites-enabled/git.sdxlive.com.conf
ssl_certificate /etc/nginx/tls/sdxlive.com.chained.crt;
ssl_certificate_key /etc/nginx/tls/sdxlive.com_rsakey.pem;

systemctl restart nginx

It produced this output:

Sep 24 17:56:10 systemd[1]: Started A high performance web server and a reverse proxy server.

My web server is (include version):
nginx 1.17.3

The operating system my web server runs on is (include version):
Ubuntu 19.10

I can login to a root shell on my machine (yes or no, or I don’t know):
yes

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot):
ansible 2.8.5

So, there is no issue with a lets encrypt SAN certificate: chrome is happy with it.
Switching to a lets encrypt wildcard certificate and restarting nginx makes chrome frown with a “invalid certificate” wince.
The wildcard certificate has just been successfully obtained from let’s encrypt.

Since then, I have switched back to a SAN certificate.

I don’t see any *.sdxlive.com certificates in CT search websites.

https://crt.sh/?q=%sdxlive.com

There were three certificates for sdxlive.com issued today, but that’s not a wildcard. It just works for https://sdxlive.com/.

You probably want a certificate that includes both sdxlive.com and *.sdxlive.com.

Hi @jean-christophe-manc

there is the certificate with the subdomain git:

CN=git.sdxlive.com
	02.08.2019
	31.10.2019
expires in 37 days	git.sdxlive.com - 1 entry

So

  • it’s not a wildcard certificate
  • and it’s invalid

Do you have an own vHost with your main domain?

OK, my bad.
I reissued another wildcard certificate with both “*.sdxlive.com” & “sdxlive.com” in alt name.
Now chrome is happy.
Thanks.
