If you want to make sure that the SSL certificate for your website is correctly installed, secure, and doesn't give any errors to your users, you can use this SSL checker.
If you have two domain names, with and without ‘www‘, make sure you added each one into your project settings. Don't forget to click "Save Changes".
If one of your domains is not secure, you'll see the mismatch error.
The error above can be caused by numerous IP addresses of the hostname.
Here are a few steps of how to fix it:
Go to this website to find out how many IP addresses your domain has.
Make sure that you have only one IP address, otherwise remove the extra ones from your domain provider's settings.
❗️The only IP address you should be using is 126.96.36.199
After removing the extra IP addresses, please contact us. You can use the chat bubble here, or email firstname.lastname@example.org.
❗️If your domain is still not secure, make sure that you cleared the cash memory in your browser and checked the SSL by opening the website in Incognito mode. In case you still have an error, contact us via the chat bubble here, or email email@example.com.
