 (1.) Rename the file 'efsws_key.pem' with 'ServerKey.pem'.
 (2.) Create an empty file named 'ServerCert.pem' with Notepad, copy the content of the certificate from CA and paste it into the Notepad.
 (3.) If you get an intermediate certificate from CA, copy the content of the intermediate certificate and paste it into the Notepad under the existing content.
 (4.) If you get a root certificate from CA, copy the content of the root certificate and paste it into the Notepad under the existing content.
 (5.) Save the file 'ServerCert.pem'
 (6.) Copy these 2 files(ServerCert.pem,ServerKey.pem) into the Easy File Server folder and replace the old ones.
