deploying azure web role application for blob storage on virtual machine IIS

I have an web role based application developed in .net MVC 4.5, We are using Microsoft Azure storage. I have published the application through VS2013 to Microsoft Azure this works fine for me. I have problem now is that I want to move application to client Azure account. I have used client's ENDPOINT setting, and Tested on my local machine, Blob storage is working fine. Document are uploading. Now I have published this application and trying to run on client virtual machine IIS server. There I have encounter an Exception saying that "External component Exception" means blob storage is not connecting or Azure sdk version Issue. I have developed using Azure sdk 2.9 and client has 2.8 sdk version. Please help.
