Most browsers only need the main CRT for the SSL certificate to work correctly. However, some, such as Firefox and mobile browsers, have trouble verifying the full chain of authority for SSL certificates. In those cases, the browser will gives errors, such as Chain Issues Incomplete or This Connection is Untrusted. If you have a site that will work on https:// in some browsers, but not others, this is the case. If your certificate does not work in any browser, then it is a different issue.
To fix the issue, you will simply need to install the intermediate certificate on your hosting server. To get the certificate, please follow these steps:
- Log into your Name.com account and click My Account on the right, and then click my products in green.
- If you have multiple products, click SSL Certificates. Then click on the SSL certificate you are having issues with.
- Next to Certificates have been issued, click Show Certificates.
- Under CA Certificates, copy the certificate below INTERMEDIATE (including the begin certificate and end certificate lines).
If you have hosting elsewhere, please give your hosting provider the Intermediate CA Certificate. Once they install it, the error will disappear. If you are hosted with Name.com, you can add the certificate yourself. To do so, follow the steps below:
- Log into your Name.com account and click My Account on the right.
- Click Web Hosting, under the my products.
- Click the blue cPanel Login button on the right.
- Under Security, click SSL/TLS Manager.
- Click Manage SSL sites under Install and Manage SSL for your site (HTTPS). (It will be the last option.)
- Under Browse Certificates, you will see a drop down menu labeled Domains. Select the correct domain name from the drop down menu.
- Click the Autofill by Domain button.
- Scroll down to the last certificate field, labeled Certificate Authority Bundle: (CABUNDLE). Paste the Intermediate certificate there.
- Click the Install Certificate button.
Once that is done, it may take a little time for the records to update, but after they do, your website will work fine in all browsers.
