Facing this issue only in IE.

Reproducible for first time in IE, from the second occurrence this issue is not reproduced.

The error we are able catch is “SCRIPT7002: XMLHttpRequest: Network Error 0x2f78, Could not complete the operation due to error 00002f78”.

    No, this is a different error code. – Ben Visness Apr 26 '17 at 22:04
  • This is probably [ERROR_HTTP_INVALID_SERVER_RESPONSE(12152 / 0x2f78)](https://msdn.microsoft.com/en-us/library/windows/desktop/aa385465(v=vs.85).aspx). Why the server is returning junk the first time is a complete mystery, since you don't show either your code or the server's code.
