My domain is: allmyloveyogurt.com
My web server is (include version): Debian 10
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 (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): 0.31.0
My problem is, the ssl of www wasn’t working.
So I added the www domain to my cert, and now both can’t work🥲
It shows net::ERR_CERT_COMMON_NAME_INVALID
Can anyone help 
thanks a lots!
It looks like it is working from here.

Hi @cindywill317 welcome to the community!
I concur with @TheEggman ...
http://www.allmyloveyogurt.com ->> https://www.allmyloveyogurt.com/ ->> https://allmyloveyogurt.com/
Your "www" vhost is working and redirecting to your apex domain (https://allmyloveyogurt.com)
And Certificate chain is correct.
I agree, allmyloveyogurt.com as wel as www.allmyloveyogurt.com send the correct certificate.
Welcome back, Maxine! 
I too have checked your certificate chain with SSL Labs and your redirects with redirect-checker.org. Everything appears to be in order.
Hi, thank you guys for replying!
Glad to know everything's fine now.
I guess it's because I re-certificate both of them by using this command
''''sudo certbot --apache -d mydomain.com -d www.mydomain.com''''
Looks like it worked perfectly... 
Anyway, thank you all for checking!
