session timeout expired

Loufus

Hello everyone
I created a custom DLL that I use to transfer files between two Nav clients
The file transfer work fine for small files, However when the size is large, the following error occurs:
‘The timeout for the operation has expired’
According to some research that I have done, I am supposed to make the following changes:
Increase the timeout of Idle Client Timeout and ClientKeepAlive

Increase connection Timeout in ISS

However, it doesn't seem to be working
My Codeunit stops running after 2 minutes (more or less)
Any idea on what I am supposed to be doing to increase the time out7
Thanks in advance
