Getting ERR_CERT_AUTHORITY_INVALID after installing SSL Certificate on Google Cloud Platform

Question

I followed this tutorial: https://www.onepagezen.com/free-ssl-certificate-wordpress-google-cloud-bitnami/ to implement SSL Certificate for my website on Google Cloud Platform. Now that I'm opening it I'm getting ERR_CERT_AUTHORITY_INVALID and I've done everything right.

All of my certificates .pem files are in my website's folder (madnumber.org) and not in example.com that I've ensured.

My Configuration file is: /opt/bitnami/apache2/conf/bitnami/bitnami.conf

here is the code:

# Default Virtual Host configuration.
<IfVersion < 2.3 >
  NameVirtualHost *:80
  NameVirtualHost *:443
</IfVersion>
<VirtualHost _default_:80>
  DocumentRoot "/opt/bitnami/apache2/htdocs"
  ServerName www.madnumber.org
  ServerAlias madnumber.org
  Redirect permanent / https://www.madnumber.org/
  <Directory "/opt/bitnami/apache2/htdocs">
    Options Indexes FollowSymLinks
    AllowOverride All
    <IfVersion < 2.3 >
      Order allow,deny
      Allow from all
    </IfVersion>
    <IfVersion >= 2.3 >
      Require all granted
    </IfVersion>
  </Directory>
  # Error Documents
  ErrorDocument 503 /503.html
  # Bitnami applications installed with a prefix URL (default)
  Include "/opt/bitnami/apache2/conf/bitnami/bitnami-apps-prefix.conf"
</VirtualHost>

UPDATE: Following a new tutorial https://techmonger.github.io/46/free-ssl-google-cloud/ but it's giving me this error:

Domain: madnumber.org Type: unauthorized Detail: Invalid response from
http://madnumber.org/.well-known/acme-challenge/1OlqUItVV8q_MTc-vkFp53nifCBtcVNftFDyRmdxKYY [00.00.00.0000]: "\n lang=\"en-US\">\n\n\t\n\t name=\"viewport\" content=\"width=device-width, initial" To fix these errors, please make sure that your domain name was entered correctly and the DNS A/AAAA record(s) for that domain contain(s) the right IP address.

Answer 1

You are facing this error because of any of below mentioned three reasons:

1. The certificate issued has already expired
2. The Browser is old
3. The website certificate and browser connection are not secure
