Certbot NET::ERR_CERT_AUTHORITY_INVALID error

Help
#1

Hello! Just installed a certificate on my site but it seems not working, saying that “sertificate is self-signed”.

My domain is: keevee.games

I ran this command: certbot-auto --apache

It produced this output: Congratulations! You have successfully enabled https://keevee.games (no errors)

My web server is: Apache 2.4.6

The operating system my web server runs on is: CentOS 7

My hosting provider: VPS

I can login to a root shell on my machine: yes

I’m using a control panel to manage my site: no

The version of my client is: 0.36.0

Hi @MusNik,

Welcome to the community forum!

I too can see that your apache webserver is serving up a self signed cert.

$ echo | openssl s_client -connect keevee.games:443 -servername keevee.games 2>&1 | openssl x509 -noout -issuer
issuer=C = --, ST = SomeState, L = SomeCity, O = SomeOrganization, OU = SomeOrganizationalUnit, CN = keevee.games, emailAddress = root@keevee.games

Have you tried gracefully restarting apache to and checking if the Let’s Encrypt issued certificate is served up?

sudo apachectl -k graceful

Gracefully restarted apachectl, nothing shanged.

Can you share the output of

apachectl -S

and your vhost config for keevee.games

Here is the output:

It appears that your conf.d/ssl.conf _default_:443 vhost is being served up first which includes the self-signed

SSLCertificateFile /etc/pki/tls/certs/localhost.crt
SSLCertificateKeyFile /etc/pki/tls/private/localhost.key

I would suggest temporarily moving that file out of the way, gracefully restarting apache, and verifying with openssl and apachectl -S that your correct vhost config is actually being served.

Hi @MusNik

there you see the problem:

you have two different configurations with the same port and the same domain name.

Merge these into one vHost and remove the other. Then restart your server.

Thank you, @Phil, @JuergenAuer

You are right, the problem was because of vHost duplicate. I fixed that by deleting VirtualHost _default_:443 part from the conf.d/ssl.conf file
