    Note:- Login method is SSO (single sign on). Not able to find what is the issue. Issue faced by some few users only. My application is running on HTTPS.

     i installed fiddler 4 on user machine who facing the issue. Many logs were logged  with status 502, when i saw  error in Raw section error is like this 

    Error: ConnectionRefused (0x274d). <br />System.Net.Sockets.SocketException No connection could be made because the target machine actively refused it<myipaddress>:443

    Hi nityanandy,

    Error: ConnectionRefused (0x274d). <br />System.Net.Sockets.SocketException No connection could be made because the target machine actively refused it<myipaddress>:443

    To solve this issue , you can try to follow these:

    According to the page prompt, first close fiddler, then look at the system's proxy settings, and see that the proxy settings are set to "Automatic Configuration > using the automatic configuration script".

     At the same time, the form prompts "Automatic Configuration will override manual settings, to ensure the use of manual settings, please disable automatic configuration", so try to uncheck the check box in front of "Use Automatic Configuration Script". Then try to open Fiddler again and enter a non-https website in the browser. The page is displayed successfully.

    The I/O operation has been aborted because of either a thread exit or an application request. (0x800703e3)

    This error may related to application version incompatibility , you could refer to this link :

    Hi,

    Looks like a firewall issue ie the other machine tells explicitely the connection is refused. You don't have a stack trace?  It happens between the web server and some other server involved in authentication maybe ?

    I don't think it is firewall issue because after 5 or 10 min application  works well. And only few user are experiencing these issue.

    The socket error usually indicates the site is down or the client is unable to reach the site.  The I/O error can happen if the client disconnected during the request.

    How much data are you moving over the wire?  Is your application restarting or you have a very large ViewState?
