Recently I was trying to test a web service. The traffic was over SSL/TLS and everything was fine. As I am better with Burp than SoapUI, I wanted to use Burp as a proxy for SoapUI. This should be an easy matter. Burp will create a custom certificate (signed by its root CA) for each site and effectively Man-in-the-Middle the connection. But this time it was different, I was getting the dreaded
Peer not Authenticated
error. This meant that SoapUI did not recognize Burp's custom certificate.- The Client Failed To Negotiate An Ssl Connection Burp Instructions
- The Client Failed To Negotiate An Ssl Connection Burp Time
- The Client Failed To Negotiate An Ssl Connection Burp Program
- The Client Failed To Negotiate An Ssl Connection Burp Suite
- The Client Failed To Negotiate An Ssl Connection Burp Form
The Client Failed To Negotiate An Ssl Connection Burp Instructions
I Googled and found some solutions such as adding Burp's CA to my certificate store (already done), adding it to SoapUI's keystore (didn't work) or using custom versions of SoapUI created for exactly this reason (again didn't work).
- How to solve “The client failed to negotiate an SSL connection” issue on BurpSuite and run HTTPs sites? Navigate to localhost:8080 from browser. If you are running BurpSuite on other ports and not on 8080, you need to. Click on CA Certificate link. You will get a certificate named.
- Step 1: Configure your browser to use Burp Suite as a proxy. We will not cover this here; we assume that you are familiar with setting up and using Burp Suite. For this example, Burp’s proxy will be listening on 127.0.0.1:8080. Step 2: Configure OWASP ZAP. Install OWAP ZAP Proxy, and make the following changes by going to Tools - Options.
After a suitably long period of weeping and gnashing of teeth I achieved salvation.

Vpntunnel='New nav' vpntype=ipsec In Mac it goes like this, Preshared key is incorrect I know the preshared key is correct.This connection was working until 2 weeks back. Dont know what went wrong. The fortigate log says ' Action: negotiate Status: failureprogress Message: IPsec phase 1 Any help would be much appreciated.

Here's how to do it:
- Modify target address to http from https
- 2.a. In SoapUI, modify the
Service Endpoint.
Changehttps://example.com
tohttp://example.com
.
Or - 2.b. Modify the WSDL and change
wsdl:address location
similarly and import it into SoapUI. - Edit Burp's listener and check
Force use of SSL
underRequest Handling.
Notice that theRedirect to port
input field will be automatically populated with 443. If your service endpoint is using a different port, modify that accordingly. - Now you can send requests from SoapUI and intercept them in Burp. Responses will appear in both SoapUI and Burp like any proxied application.
- Be sure to remove the
Force use of SSL
after you are done. Otherwise you will be wondering why gmail is available under http in your browser (likemesomeone I know).

### My Story
First I thought it should be a problem of app itself! so I dived deep inside the app. I used static analysis to understand what it is doing. but it was somehow confusing and complicated. so I tried another way; dynamic analysis. I started Burp and trying to monitor the traffic.

but there was a problem! This error was occurring repeatedly and I couldn't do the purchase while system proxy setting was set to my Burp IP! I had set the cert; so I didn't know the cause of the problem!

I saw a new phrase I didn't know what is it; `SSL Pinning`. But I remembered a script from [codeshare.frida.re](https://codeshare.frida.re) named `Universal Android SSL Pinning Bypass with Frida`. So this is the solution to bypass this #&%^#@!

It took a lot of time to analyze statically and finding out the solution of `SSL Pinning` problem. But I learned a lot! :P
After bypassing SSL Pinning it was so easy to capture the traffic to the back-end server.
