Nginx – SSL will not work on Android mobile

I bought Comodo SSL from Namecheap. Now, the SSL works fine on desktop, I am getting a "This Connection is not private" on mobile phone.. on my chrome on Android

Here is my virtual host file:

server {
       listen         80;
       server_name    www.-------------.com;
       return         301 https://www.-------------.com$request_uri;
}

server {

    listen 443 ssl;

    root /var/www/-------------.com/html;
    index index.html index.htm;

    ssl_certificate /etc/nginx/ssl/ssl-bundle.crt;
    ssl_certificate_key /etc/nginx/ssl/navarrarpg_com.key;

    ssl_session_cache shared:SSL:10m;
    ssl_session_timeout 10m;

    ssl_prefer_server_ciphers on;
    ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES:!aNULL:!MD5:!DSS;

    server_name www.-------------.com;

    location / {
        try_files $uri $uri/ =404;
    }
}

Here are the four files I recieved:

• AddTrustExternalCARoot.crt
• COMODORSAAddTrustCA.crt
• COMODORSADomainValidationSecureServerCA.crt
• ————-_com.crt

Of course, I then used the command to bundle them all up nicely to get the bundled certificate plus the key using the other command.

Now, when I go to https://www.digicert.com/help/ and I type in my address… it says that I installed it correctly.

I checked out my cert installation to make sure I got the chain right:

• Comodo RSA Certification Authority
  • Comodo RSA Domain Validation Secure Server CA
    • ————-.com

I used the following command:

cat -------------_com.crt COMODORSADomainValidationSecureServerCA.crt COMODORSAAddTrustCA.crt AddTrustExternalCARoot.crt > ssl-bundle.crt

from this guide: https://gist.github.com/bradmontgomery/6487319 to get the ssl bundle cert.

Why isn't my website showing up securely on my Android mobile but is on my desktop?

I get NET::ERR_CERT_AUTHORITY_INVALID error on my phone
