Different "underlying connection closed" errors RRS feed

  • Question

  •  

    I'm seeing different "underlying connection closed" errors  when we are trying to connect to a web site using HTTPS connection:

     

    The underlying connection was closed: Could not establish secure channel for SSL/TLS

    System.Exception: Error Sending:The operation has timed-out.

    System.Exception: Error Receiving: The underlying connection was closed: An unexpected error occurred on a receive.

     

     

    Most of the times I'm seeing the first two errors, however, these are sporadic.

     

    The call flow to the web site is something like below:

     

    • My Application (VB6 app) calls a web service on web server, which connects to the .NET component on app server, which again connects to the web site, through a proxy server.

    Please note that the web servers and app servers are in load balacing condition, AND, we are using .NET 1.1 framework with SP1.

     

    Could someone advise how we can avoid these sporadic errors?

     

    Thanks in advance.
