SCRIPT7002 XMLHttpRequest Network Error 0x2ef3 Could not complete the operation due to error 00002ef3

Question

I keep receiving this error when I do some Ajax calls     It may even be something to do with Geocoding but I really have no idea how to capture the error to display something useful to users    or even how to solve the problem as it seems to just be referencing some kind of pointer or something  S 0x2ef3     SCRIPT7002  XMLHttpRequest  Network Error 0x2ef3  Could not complete the operation due to error 00002ef3     An image might be more helpful than the error message     Any ideas at all   My code fires off 10 ajax calls in 1 second to be processed by geocoding server side    The error comes up intermittently  Sometimes I get geocoded results and sometimes I get that error  I would say I get it 10  of the time  It completely stops the ajax call from firing my error handler in jQuery

I just want to add what solved this problem for me, as it is different to all of the above answers.

The ajax calls that were causing the problem were trying to pass an empty data object. It seems IE does not like this, but other browsers don't mind.

To fix it I simply removed data: {}, from the ajax call.

I had this problem  a an AJAX Post request that returned some JSON would fail  eventually returning abort  with the      SCRIPT7002  XMLHttpRequest  Network Error 0x2ef3   error in the console  On other browsers  Chrome  Firefox  Safari  the exact same AJAX request was fine   Tracked my issue down - investigation revealed that the response was missing the status code  In this case it should have been 500 internal error  This was being generated as part of a C  web application using service stack that requires an error code to be explicitly set    IE seemed to leave the connection open to the server  eventually it timed out and it  aborted  the request  despite receiving the content and other headers   Perhaps there is an issue with how IE is handling the headers in posts   Updating the web application to correctly return the status code fixed the issue   Hope this helps someone

Incase none of these solutions were  clear  enough  essentially IE Edge is failing to parse your  data  field of your AJAX call properly  More than likely you re sending an  encoded  JSON object   What Failed   data       Key     Value       What Works   data     Key   Value

SOLVED   I only observed this error today  for me the Error code was different though      SCRIPT7002  XMLHttpRequest  Network Error 0x2efd  Could not complete   the operation due to error 00002efd    It was occurring randomly and not all the time  but what it noticed is  if it comes for subsequent ajax calls  so i put some delay of 5 seconds between the ajax calls and it resolved

I received the same error  SCRIPT7002  XMLHttpRequest  Network Error 0x80004004  Operation aborted   in our case it was because of JavaScript s same origin policy    Our web app was making a JQuery AJAX call to our server on Port 8080  The call was getting intercepted and re-routed over SSL  due to server rules mandating that incoming traffic use SSL     Once we made our web app load through the SSL port the issue was fixed

I have stumbled across this questions and answers after receiving the aforementioned error in IE11 when trying to upload files using XMLHttpRequest   var reqObj   new XMLHttpRequest       event Handler reqObj upload addEventListener  progress   uploadProgress  false   reqObj addEventListener  load   uploadComplete  false   reqObj addEventListener  error   uploadFailed  false   reqObj addEventListener  abort   uploadCanceled  false      open the object and set method of call  post   url to call  isAsynchronous true  reqObj open  POST    rootUrlService rootUrl    Controller UploadFiles   true      set Content-Type at request header for file upload it s value must be multipart form-data reqObj setRequestHeader  Content-Type    multipart form-data       Set header properties   file name and project milestone id reqObj setRequestHeader  X-File-Name   name       send the file    this is the line where the error occurs reqObj send fileToUpload     Removing the line reqObj setRequestHeader  Content-Type    multipart form-data    fixed the problem   Note  this error is shown very differently in other browsers  I e  Chrome shows something similar to a connection reset which is similar to what Fiddler reports  an empty response due to sudden connection close    Also  this error appeared only when upload was done from a machine different from WebServer  no problems on localhost

This issue happened in my project because of an ajax GET call with a long xml string as a parameter value  Solved by the following approach  Making it as ajax post call to Java Spring MVC controller class method like this      ajax       url   controller Method Name html variable name   variable value      type   POST       data                 xmlMetaData   xmlMetaData    This variable contains a long xml string            success  function response                console log response                 Inside Spring MVC Controller class method    RequestMapping value   controller Method Name     public void controller Method Name  RequestParam  xmlMetaData   String metaDataXML  HttpServletRequest request       System out println metaDataXML

We also encountered similar problems  However  setting the charset as noted in the previous comment did not help  Our application was making an AJAX request every 60 seconds and our webserver  nginx  was sending Keep-Alive timeout at 60 seconds   We fixed the problem by setting the keep-alive timeout value to 75 seconds   This is what we believe was happening    IE makes an AJAX request every 60 seconds  setting Keep-Alive in the request  At the same time  nginx knows that the Keep-Alive timeout value is ignored by IE  so it starts the TCP connection close process  in the case of FF Chrome this is started by the client  IE receives the close connection request for the previously sent request   Since this is not expected by IE  it throws an error and aborts  nginx still seems to be responding to the request even though the connection is closed    A Wireshark TCP dump would provide more clarity  our problem is fixed and we do not wish to spend more time on it

Upping the directive in the virtualhost for KeepAliveTimeout to 60 solved this for me

User · Answer

With the Apache 2 change KeepAliveTimeout   set it to 60 or above
