CONNECT requests are not supported - java

I am writing an HTTPS proxy in play framework, yet every time I try to run it on a website that has ssl encryption I am getting this error in my server:
akka.actor.ActorSystemImpl(play-dev-mode) Illegal request, responding with status '400 Bad Request': CONNECT requests are not suppo
rted: Rejecting CONNECT request to '//any.website:443'
The proxy works well on HTTP, yet HTTPS is the problem. I tried changing my application.conf to have a port destined to work on HTTPS, but when I try to run it with the keystore i setup using the keytool command I am getting the following error in my browser:
Secure Connection Failed
The connection to the server was reset while the page was loading.
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the website owners to inform them of this problem.
Any workaround to allow HTTPS on a play framework proxy server?

ERR_CERT_AUTHORITY_INVALID when accessing same hostname with different port

We have a splunk instance which is exposed to internet via say https://splunk.mycompany.com
When we access the above URL browser says connection is secure meaning all certificates are ok.
Now splunk REST API service is running on port 8089. So to access splunk REST API we have to hit
https://splunk.mycompany.com:8089
Whenever we are hitting the above URL we are getting certificate issues and browser is saying "your connection is not private"
Error is: NET::ERR_CERT_AUTHORITY_INVALID
As I am still accessing the same hostname via https (and a new port) it should establish a secure connection. But why it's failing to validate certificate authority?
Edit: I have been told by the splunk team to take ther certificate of https://splunk.mycompany.com and install in the java keystore in the machine from where the REST API call is being made. They also told this is working for otheres. My question why it is even needed?
You should enable SSL on port 8089 via server.conf file.
Have a look at the Splunk Documentation here: https://docs.splunk.com/Documentation/Splunk/9.0.0/Security/ConfigTLSCertsS2S

SSL client (Java) is not sending a certificate back to the server in two-way SSL handshake

We are trying to access a restful web service resource hosted on IIS server with https protocol.
When we disable TWO WAY SSL Auth (server side validation of client certificate disabled) everything works fine.
When the IIS imposes TWO WAY SSL (server side validation of client certificate enabled) we are getting the below exception:
403 - Forbidden: Access is denied.
You do not have permission to view this directory or page using the credentials that you supplied.
We are using java 1.8 update 102, IIS server 7.5 and TLS 1.2 for ssl
For detailed issue please open the below link:
For details SSL Debug log, certificates, client program
It will be great help if someone help us.
Thanks!
See this warning in the SSL log:
no suitable certificate found - continuing without client authentication
Your server is sending a list of accepted CAs to request a client certificate, but your client does not find a suitable one. It seems your keystore has the correct certificate. Ensure that your certificate is correct, for example installing it in the browser and navigating to a protected resource
May be it is a configuration issue of your Java client. Please read HttpClientBuilder documentation carefully
System properties will be taken into account when configuring the default implementations when useSystemProperties() method is called prior to calling build().
You did not call useSystemProperties().

Java standalone proxy program

I am making a proxy application for a browser. It has to use only the standard libraries. So far, I've managed to create the server. When trying to access a web page from a client, i get the following information:
CONNECT gmail.com:443 HTTP/1.1
User-Agent: Mozilla/5.0 Firefox/49.0
Proxy-Connection: keep-alive
Connection: keep-alive
Host: gmail.com:443
My question is: what to use in order to handle the requests? How to handle a file download?
Once you get that CONNECT command, do what is asked: create the upstream connection, and return the appropriate success/failure response. If the upstream connection was successful, all you have to do now is copy bytes in both directions, simultaneously. The endpoints will take care of all SSL issues, uploads, downloads, etc. You have no further role to play.
The general behaviour of a proxy is as follows:
Receive request from browser
Make a request to the actual server, resolving all redirects if necessary
Get the response from server and passit on to client
I am not getting into complications of changing request/response headers, caching etc.
Now from the above, you are making a SSL connection to gmail.com refer.
The browser is actually sending correct request, in this case you need to implement the handshake and connect to gmail with HTTPS offloading SSL on your side and sending the response received to the browser through the negotiated SSL with the browser.
Suggestion is to use HTTP instead of HTTPS, if this is not a production grader system and try out the concept first

JavaScript and Java WebSocket SSL Connection Error

I am writing a browser plugin for a webpage which runs over HTTPS. My backend is in Java, so creating a websocket between javascript and java. But the websocket is giving following error.
WebSocket connection to 'wss://127.0.0.1:8080/' failed: Error in connection establishment: net::ERR_SSL_PROTOCOL_ERROR
Can someone tell how to remove this error?
In order to use SSL in development machine create auto-signed SSL key a certificate for '127.0.0.1' and put a web server locally with HTTPS support, like Nginx, in front of your Java app, or if you are using a Java based web server look for HTTPS configuration (and WebSockets support as well). This way you'll be able to tests secure transport.

Remote Host closed connection during hansdshake while connecting to ISA server from SOAP UI

We are trying to connect to ISA server over HTTPS from SOAP UI client. The ISA server redirects the URL to the required windows server within the organization.
When u send a request from SOAP UI client, we get "Remote host closed connection during handshake" error.
We have not changed any parameters on SOAP UI client or as read in few other blogs have not imported any certificates. Is importing certificate mandatory?
How do we go about to get succesful connection.
-Anand
The issue is resolved. The cretificate on ISA server was not deployed properly. The network admin team re-depolyed the certificates and the rule works fine.
