Have you set the HttpRuntime element with proper values in Web.Config file? For such big files it will take more time and thus you need to keep the request/response alive till then and also increase the size of request.

Read:
httpRuntime Element (ASP.NET Settings Schema)[^]

You would need to increase executionTimeout & maxRequestLength

Even after doing these, if there is some error/issue tell us what it is.
