Net::err_cert_common_name_invalid

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. https://crt.sh/?q=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:mahabazaaronline.com

I ran this command:sudo certbot --apache -d mahabazaaronline.com

It produced this output:/etc/letsencrypt/options-ssl-apache.conf has been manually modified; updated file saved to /usr/lib/python3/dist-packages/certbot_apache/options-ssl-apache.conf. We recommend updating /etc/letsencrypt/options-ssl-apache.conf for security purposes.

My web server is (include version):2.4.18

The operating system my web server runs on is (include version): Ubuntu 16.04

My hosting provider, if applicable, is: DO

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, or provide the name and version of the control panel): no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): 1.9.0

Everything went well. My e-commerce store's front end and admin end worked well with https://mahabazaaronline.com. I checked if the certificate works for www.mahabazaaronline.com, it gives me error NET::ERR_CERT_COMMON_NAME_INVALID
Strangely, from that point onward, home page gives me an error (Whoops our bad! Typical magento error message for a bad url) but all pages work properly. What could go wrong with perfectly working URL?
Can someone please help me, That would be very helpful

Hi @sujathaupadhyaaya

that error is expected.

Your command

doesn't have the www version. Add a second -d with the www version and use that certificate.

Now that I have created this cerificate already, can I run this command
sudo certbot-auto --apache -d mahabzaaronline.com -d www.mahanazaaronline.com
now? will it safely overwrite?

Sorry, I am new to this...was going through some documentation ...maybe I should use certonly as below
certbot certonly --cert-name example.com -d example.org,www.example.org

@JuergenAuer thanks so much for the help and time. I did generate a new certificate including both www & non-www,, here is the result of the command that I ran
vismaya@vismaya-magento231:/usr/local/bin$ sudo certbot-auto --apache -d mahabazaaronline.com -d www.mahabazaaronline.com

You have an existing certificate that contains a portion of the domains you
requested (ref: /etc/letsencrypt/renewal/mahabazaaronline.com.conf)

It contains these names: mahabazaaronline.com

You requested these names for the new certificate: mahabazaaronline.com,
www.mahabazaaronline.com.

Do you want to expand and replace this existing certificate with the new
certificate?

I don't see that. I see content. Checked with my browser. And see the screenshot - https://check-your-website.server-daten.de/?q=mahabazaaronline.com#screenshots

But your configuration is buggy:

is a 404 - https + non-www

http and https + www redirects with a ?SID=, https + non-www not. With the SID, content is visible.

But that's a configuration problem of your system you have to fix.
