NGNIX how to specify SSL intermediate cert

The process of specifying intermediate certificate is same across server because it is really done on the crt file. Here is how to be done

First of all verify if there is any issue with the certificate chain by checking in the SSL checker.

Now if the above test specifies that it does not work on certain platforms, we need to do the below to include the intermediate certificates.

$ cp example.com-2013.crt example.com-2013.pem
$ cat intermediate.crt >> example.com-2013.pem


Now that we got the certificate file that includes the chain, specify it is the SSL default file like mentioned in another post.
