Hi, I am trying to intercept web communication from an Android device (emulated from genymotion). 1. I can access to http://burp/ 2. Installed at system-level burp certificate on the android device. 3. Also can intercept any http request 4. But nothing that goes through https works.

Hi, Can you provide us with more information about how you have installed the Burp CA certificate on your Android device? Just to clarify, if you try to navigate to well known sites (google, portswigger.net etc) in the browser on your Android device, you see the same error, the site does not load ?

I am using a macbook pro. And I have tested it since both versions of burp community and burp professional. Certificate I have installed in two different ways: 1. accessing http://burp, downloading the certificate to the mobile and installing it at user level (both for the wifi option and for the vpn). 2. I have also tried to export the certificate from burp, modifying the .der to .pem with openssl, configuring it to be accepted by android and uploading it inside the android, to the /system/etc/security/cacerts/ folder. On the other hand, I have also tried to intercept from a physical iPhone device (configuring cert and everything correctly). In this case the https protocol works. But goes very very slow (1-2min for a simple https://google.com request). And from time to time it does not load the web returning in the dashboard burp: "1613144704176 Error Proxy [10] The client failed to negotiate an SSL connection to www.google.es:443: Remote host terminated the handshake" After that, and making same configurations, I have tested it from a windows computer and the https protocol works fine. So the fault is located between burp and macOs (macbook pro 2019). pd: I would like to send some capture of the configuration and burp but I do not see that it is possible

Hi, If you send us an email at support@portswigger.net then you can attach screenshots. That may be the best approach in this instance so we can see exactly what your configuration is. I did actually run through setting Burp up on an Android device (using the Nox emulator) on a Mac towards the end of last week (in order to test this) and was able to do this successfully. The steps in the following blog post helped with this process: https://blog.ropnop.com/configuring-burp-suite-with-android-nougat/
