My clients report this error from time to time. They receive new::ERR_EMPTY_RESPONSE and the upload retries the maximum number, then fails. Most recent occurrence was on OSX Maverick, Chrome. It happens on Safari as well.
The problem is not widespread, it occurs on a relatively small % of clients.
Fine Uploader 5.1.3
s3.jquery.fine-uploader.js:3878
new::ERR_EMPTY_RESPONSE
s3.jquery.fine-uploader.js:29
POST request for 0 has failed - response code 0
Received an empty or invalid response from the server!
Here is a console screenshot
The issue is with your server or network. The browser complains the the preflight request is being returned with a completely empty response. This is not an issue with Fine Uploader. You'll need to examine logs on your signature server, or perhaps there are some network issues on your end or your client's end.

I have recorded script in jmeter V3.3 via IE browser and then done correlation. When I run this script, then it is receiving internal server error 500 in response, however it works fine manually in IE browser and also while recording this scenario, it does not occur.
I also cross verified Header manager with Request Headers in network IE F12 Developer tool and it is uptodate.
Sampler Request
Http Get Request
It is simply Get request. I really appreciate for your help to handle this error in jmeter.
I hope you have compared both Request Headers one from IE Browser and from JMETER request headers to check if anything is not missing to pass. And also along with any dynamic id is not missing.
You are likely not checking for expected results with each step. As a result, you are receiving an HTTP 200 correct response page prior to your HTTP 500, but the content of the page is out of context with the expected results for the business process. When you make your next request the state of the application is not appropriate to your request. As an unhandled condition by the developer you are greeted with an HTTP 500 screen dump.
Most likely cause: Unhandled dynamic data component.
I have read and tried the solutions shared in the previous posts for this error but nothing helped me to fix this. Kindly help.
I am making a HTTPS API call. A very simple call which accepts a 2 KB JSON message via POST method and sends a one word acknowledgement. It works perfectly fine in Postman tool. In JMeter, no. of threads (users) is kept as 25. It works perfectly fine one time with all 25 success response and at times getting few failure response as
Response code: Non HTTP response code: java.net.SocketException
Response message: Non HTTP response message: Unexpected end of file from server
No consistency at all. I have also tried with both enabling and disabling "use keepalive" checkbox. Both giving me all success one time ; few/all failure at another time with the above error. Please help. Thank you.
Below are the JMeter settings:
HTTP Header Manager : Content-Type - application/json
HTTPRequest sampler : protocol - HTTPS
Server Name or IP : project server name
Method : POST
PATH : The required path with https authentication details passed as parameters
IMPLEMENTATION : Set to JAVA (HTTPCLIENT4 was giving me “443 failed to respond” error)
Add header
Connection Keep-Alive
Both errors (Java implementation and Apache HTTPClient4 implementation), are essentially saying the same thing: The server closed the connection, without providing any response. I think there could be the following reasons:
Authentication problem. If server side checks authentication before processing a request (e.g. using Spring), it may be rejecting your request, it may be not bothering with any response if authentication is not considered correct.
Request Issue. Some less noticeable properties of the request you send via Jmeter are different from what you send in Postman. It could be some minor thing with formatting, or some headers server expects. Some of such inconsistencies can also cause Load Balancer (if you use one) to reject request before it's delivered to the server.
Certificate issues. Since you are using HTTPS, you need to make sure your certificate is setup correctly on JMeter side.
So I suggest:
Review server logs and see if your request makes it to the server. If yes, you might be able to see how it was rejected. If not, you need to trace back and see who rejected it (LB, authentication, etc)
Compare headers and body sent by JMeter vs Postman line to line (use TCPDump for example to obtain it).
SCRIPT7002: XMLHttpRequest: Network Error 0x2ee4, Could not complete the operation due to error 00002ee2.
In the developer tools Network Panel, I notice that the Result is stated as (Aborted). All other browsers work (chrome, firefox etc.)
00002ee2 is a timeout error code. If you run Fiddler, do you see the request actually hit the wire? If so, how long does it take for a response to be returned?
Is the request "interesting" in any way (e.g. to an Intranet site, or requiring NTLM authentication, or anything like that)?
I have an IOS App that sends HTTPS request to a server, using NSURLConnection, it works without any issue.
Now, I'm trying to put this App on OSX and to reuse code from the IOS App. It's the first time I'm developing on OSX, so I'm a beginner ;-)
My OSX get an exception when I'm sending my first HTTPS requests (using Post), the exception is about NSURLConnectionLoader (it ends at libc++abi.dylib __cxa throw and it seems it has been raised due to security issue Security::KeyChainCore...).
Next, on the debugger, if I click many times on continue, the request is successfully sent and I'm get the correct answer from the server.
The following requests that are sent are working fine (no exceptions), only the first one has issues.
Any idea? Any differences between OSX and IOS for NSURLConnection?
Thanks for the help,
Sebastien.
I have an embedded web server with a self-signed SSL certificate. After I get past the Web Browser's warning about the SSL Certificate being self signed, I am seeing a difference between IE8 and Firefox 3.5.5.
In IE8, if I try to download a PNG file, it will download every time.
In FireFox, it will give me an error every other time.
The error message is this:
Secure Connection Failed
An error occurred during a connection to 192.168.1.100.
SSL peer was unable to negotiate an acceptable set of security parameters.
(Error code: ssl_error_handshake_failure_alert)
*The page you are trying to view can not be shown because the authenticity of the received data could not be verified.
*Please contact the web site owners to inform them of this problem. Alternatively, use the command found in the help menu to report this broken site.
What is causing this? Why does one browser work all the time and the other only works every other time?
It's hard to say without looking at the packets. If I had to hazard a guess, it would be that on the second request, Firefox is trying to resume the SSL session, and for some reason, the server doesn't like that. On the next request, Firefox doesn't try to resume, and it succeeds again. Maybe?
