SSL warning only on mobile and only with www

Help
1

My domain is: dallaspetsalive.org
My web server is (include version): apache 2.4.6
The operating system my web server runs on is (include version): CentOS 7
I can login to a root shell on my machine (yes or no, or I don’t know): yes

Hello, I have an issue where only on certain browsers, and only when typing the address with http://www. a security warning is displayed. Edit: also worth noting, it appears to only happen on a phone, not a desktop.

I used CertBot for my certificate, and it’s been renewed.

Can anyone help me fix this?

Here is the error: https://i.postimg.cc/Jh0V9VDm/Screenshot_20180924-132141_Samsung_Internet.jpg

Hi,

Your certificate include only the root domain, not the www…

You should use the certificate with both hostnames…

Please try this command:
sudo certbot --expand -d dallaspetsalive.org -d www.dallaspetsalive.org

Then make sure your web server is using this certificate than the old one… (Restart your web-server when necessary)

Thank you

This appears to have worked, thanks!
