Error: An established connection was aborted by the software in your host machine

Hello Experts !

I am new to SOPHOS and Socket programming and trying to connect my C# web application to SOPHOS antivirus using ICAP protocol. I have installed Sophos Endpoint Security and Control, version 10.6 and using the following post to connect.

https://community.sophos.com/products/endpoint-security-control/f/sophos-endpoint-software/9420/sophos-sav-di-icap-code-sample 

I have also tried using SAVDICLI class as shared by Jak in that thread but it is also not working for me.

I am able to establish connection but it throws an exception while sending file stream to SAV with following message...

{"An established connection was aborted by the software in your host machine"}

Do anyone know how to correct this?

I am suppose to scan uploaded file and restrict it to be saved if infected else prompt user that file has been saved. Do any one know where i can found ready to use snippet for this with SAV?

Regards
Harmeet
