Problem

Your ESSL certificate has a double SHA-1 root, the green bar do not display on your browser:

Introduction

With the accelerated deprecation of SHA-1, it is important that the end-entity certificate (your certificate) and any intermediate certificates in the certificate chain use the SHA-256 hash algorithm. Doing so will prevent end users from receiving a downgraded user experience when connecting to your site. When you order a certificate from SSL247®, by default it is signed with SHA-256 and chains to an intermediate that is also signed with SHA-256.

Extended SSL Certificates (SHA-1 & SHA-2) chain back to CA's Root-R2 certificate. Some ExtendedSSL customers make use of a cross certificate that allows the ExtendedSSL Certificate to chain back to Root-R1 instead. The advantage at the time was that Root-R1 had greater ubiquity and extended the compatibility of the ExtendedSSL certificates. Root-R2 is now present in all major operating systems and devices and use of the cross certificate should no longer be a concern. The cross certificate counts as an intermediate certificate in the chain; since the cross certificate is a SHA-1 certificate, its usage may cause a downgraded user experience in Google Chrome and/or Mozilla Firefox even if you're using a SHA-256 ExtendedSSL certificate.

Browsers prefer chain building based on what is sent by the server, so when a SHA-1 intermediate / cross certificate is sent, the browser will prefer that over other, even shorter chains. That’s why it’s important to configure your server to send down the correct (and minimum number) of intermediate or CA Cross certificates.

Solution

See below the corresponding instructions for removing the EV Cross Certificate.

Microsoft IIS

1. Click Start > Run. Type MMC and press Enter.
2. Go to File > Add/Remove Snap-In
3. Choose Certificates and click Add
4. Choose Computer Account followed by Local Computer
5. Click Finish followed by OK to return to the main MMC screen.
6. Click [+] next to Certificates - Local Computer > Intermediate Certification Authorities > Certificates
7. Sort the list by Issued To and scroll down to your certificates.
8. Find the certificate Issued To: "GlobalSign" expiring on 1/28/2028
9. Right Click the entry and click Delete
10. Click Yes to confirm deletion of the Intermediate certificate
11. Close out the MMC. You do not have to save changes to the console settings.
12. Restart IIS so that your cert now chains to Root-R2

Apache

1. In your httpd.conf or ssl.conf file, check the files referenced by SSLCACertificateFile, SSLCertificateChainFile, and SSLCertificateFile..
2. The certificate you are looking to remove is:

3. Once you have located and removed the EV Cross Certificate, restart Apache:

   sudo service httpd restart

   (Replace httpd with apache2 on Debian/Ubuntu based systems)

NGINX

1. Find the entry for ssl_certificate and open the referenced file in a text editor
2. Remove the following certificate from the chain:
