400 Unable to forward request due to: Timeout waiting for connection

Hi Cheenath,

Has this bug been fixed?  I am still receiving a 400 "Read timed out error" when the "Content-Type" is set to "multipart/form-data".  Any updates, would be greatly appreciated.

-Thanks

The issue addressed in this thread, which was fixed in August 2008, has recently cropped up again. We are again experiencing "400 Unable to forward request due to: Read timed out" when running the same form submission thru remotefunction that was originally complained about.

Currently the form post is actually successful but returns the above error. This is different from the previous case where the post failed.It is not a file upload but a form post that has been working for several years (except when it has not.)

Somehow the issue got fixed last year so hopefully that could happen again. According to cheenath it is Bug #192181. Our case # was 01937347.

Can I get a update of this issue. I am still getting Read time out error when I am trying to upload a file to 3rd part services. But other services like getToken, login (post method), logout works perfectly using the same remoteaction method. 

So any help is really appreciate. 

function uploadDoc() {
 
var fd = new FormData();
var file = document.getElementById('filedata').files[0];
fd.append("filedata", file);
fd.append("filename", file.name);
fd.append("holidex", 'ABCD');

sforce.connection.remoteFunction({
url : '<https://endpointurl.com>',
requestData: envelope,
requestHeaders: {"Authorization": "Basic XXXXXXXX=", "Content-Type" : "multipart/form-data"},
method: "POST",
onSuccess : function(response) {
alert("Success " + response);
},
onFailure : function(response) {
alert("Failed " + response);
}
});

I am still getting the readtimeout error. Any help is really appreciate. 

FYI.. I am trying v25.0 connection.js
