Recently we observed that Websocket connection is failing only on latest Chrome version 56.0.2924.87
It is working is rest of the browsers(ff,ie,safari) and works fine in previous Chrome version 55
Below is the error that i see
WebSocket connection to 'wss://abc.abcserver.com/ws-xmpp' failed: Error in connection establishment: net::ERR_CONNECTION_CLOSED
Did anyone face similar issue.
Having the same issue on dozens of PCs here.
Re-creating the users' Chrome profile has resolved the issue, but Google needs to fix this.

I'm using BurpSuite to intercept the HTTP/HTTPS requests sent when logging in on https://www.nike.com/. I'm trying to achieve this with the following step:
Opening BurpSuite and Firefox
Turning on the proxy intercept
Turning on FoxyProxy on Firefox
Opening the website and trying to logging
These steps usually work for me, but in this case, I'm getting a "we are unable to connect to our servers" error without anything appearing on the intercept tab when trying to logging (I have tried turning off the intercept feature but it still yields the same issue, so I think it might be a proxy and certificate problem).
To clear things up:
I'm running the latest versions of BurpSuite and FireFox.
I have installed and reinstalled the BurpSuite certificate using this guide.
I've tried all of this on my iMac, MacBook and iPhone all of these devices yield the same issue
Here bellow is the error message I'm getting:
Here are my BurpSuite Proxy setting:
(in the Certificate tab I just have Generate CA-signed per-host certificates selected)
I have been using BurpSuite for over 2 years now and it's the first time I'm facing such an issue, any help is appreciated
I have shared my question with the Portswigger support (the team behind BurpSuite) and got the following response:
Hi
Thanks for your message.
We have reproduced the issue in our testing environment.
It looks like Nike.com are performing a fairly sophisticated check to
stop automated tool from accessing parts of their site.
Please let us know if you need any further assistance.

I am a total newbie which has started learning Ruby so please be patient with me.
I am doing Ruby challenges where I need to run a Ruby file that launches a web server on my computer. First I run this application in command line with a command:
ruby app.rb
Then I paste this URL to my browser and access to my local server:
http://localhost:4567
On this local web page I click the link that gets connected to a web server on Internet where I should get authenticated. Till this moment everything works good, but during the authentication I have got an error. If there wasn’t any error during my authorization, the application would retrieve my profile data from the internet server. This is the error that I am getting:
Faraday::SSLError at /callback
handshake alert: unrecognized_name.
I have been trying to resolve this problem for two days. What I have done:
1) I think this error is connected somehow with Java. I tried to run this application with all versions of Java (6, 7, 8) as people said they had the same problem when they updated to a higher java version. Unfortunately, my version of Ruby doesn’t accept Java 6.
2) Possible solution which was posted here SSL handshake alert: unrecognized_name error since upgrade to Java 1.7.0), the same as here in 20 similar posts in Stackoverflow about "handshake alert: unrecognized_name" error, where it is suggested to set the jsse.enableSNIExtension property. But I couldn’t understand any of those answers, specifically, where to apply this code. Then I found this link https://community.jivesoftware.com/docs/DOC-140837 where it was advised to open the Java Control Panel (I did it through System Preferences Java). I went through the Java tab and clicked View and added “-Djsse.enableSNIExtension=false” to the Runtime Parameters and applied it.
3) Another possible solution was found here Disable SNI Extension for Ruby net/http - Using IP address with SSL/TLS (the answer given by ZebGir) but I didn’t find the file *http.rb in my .rvm or even within my whole system.
Please advise any hint or link with the possible solution for my issue.
My system is Mac OS X El Capitan.
RVM version 1.27.
Java version 1.8.
Have you tried disabling the ssl setting for your the faraday library? Something like:
connection = Faraday.new 'https://example.com', :ssl => false

I'm running POSTMAN sync (sync data across devices) behind a network proxy and it is not working. Apparently it's not honoring the global proxy configuration in my system. Login in and upload is working fine. Only the sync has the issue.
I'm using
Ubuntu 14.04 LTS 64bit
Chrome Version 47.0.2526.106 (64-bit)
Postman version 3.2.9
I have also tried restarting and reinstalling POSTMAN with no luck.
The most likely cause is that your proxy does not allow websocket connections that Postman sync uses for data synchronization. Check for error messages in Postman's DevTools window
Here is a good description of how to debug this issue.
First I'd like to apologize if this question has already been answered on other posts.
I'm pretty new in WebSockets and WebRTC and here's my scenario.
I created an MVC4 application in VS 2012 and install the a sample WebRTC project via nuget package manager console (followed the steps here: http://xsockets.net/blog/tutorial-building-a-multivideo-chat-with-webrtc).
This seems to work fine on my local machine. I deployed the code on our https server (running on IIS6) and I changed the connection string to handle the https connection (code below:)
peerBroker = new XSockets.WebSocket("wss://mydomain.com:443/CustomBroker");
I then hit the URL and I got an error that says:
WebSocket connection to 'wss://mydomain.com/CustomBroker' failed: Error during WebSocket handshake: Unexpected response code: 401
Does anyone have an idea as to what I'm missing here?
You cant just change the connectionstring to be wss.
Have you configured XSockets to run over wss?
See XSockets Configuration
I'm using XCode 4.0.2 to upload my iPhone app to the iTunes app store but get the following error messages:
Failure instantiating web-service client
An exception has occurred: Unable to open url: https://contentdelivery.itunes.apple.com/WebObjects/MZLabelService.woa/ws/MZITunesProducerService?wsdl
Could not connect to Apple's web service
Unable to authenticate the package: 450416349.itmsp
I've got the latest Java version (1.6) and have double checked the network settings in the Java preferences.
Any ideas?
Got to the bottom of it. Running a TCP dump on our firewall discovered that some (but not all) of the requests that XCode made were using the configured proxy, and others were not.
We allowed the proxy to be bypassed completely to test and it all worked fine.
Have you tried using Application Loader? Try that and see if it works. Hope this helps.
