Hi Akki, Thanks for reporting this. What errors are you seeing in the Event log? Have you tried disabling TLSv1.3 on your Proxy listener? You can do this by selecting a listener > Edit > TLS Protocols > Use custom protocols.

Hi, Are you able to send an email to support@portswigger.net with screenshots of your setup (proxy details in your iPad and Burp settings) so that we can investigate this further for you?

Hi, Can you clarify what happens when you try to browse to the site http://example.com in the browser of your mobile device? I just want to confirm the integrity of the initial connection that you have setup. If you want to send us an email at support@portswigger.net and include some screenshots of what you are seeing so that we can see exactly what is happening then please feel free.

Hi Mohammed, We received the email that you sent into us with this issue and have just replied - it might be easier (in terms of sharing information/screenshots) to continue troubleshooting via email so we will await your response there.

Hi, Are you able to clarify what issues you are facing installing the Burp CA Certificate on your device?

Hello, Any updates on this ? I am facing exactly the same issue. Proxy is configured as per the instructions you posted but can’t see any traffic on my burp and can’t even download the Certificate. Safari and Chrome timeout. iPhone XR iOS 14.7.1 Any help would be appreciated.

Hi Mehdi, If you cannot see any traffic from the browser on your device in Burp then that would suggest there is something wrong with the connectivity between the device and the machine that Burp is running on. If you open a browser on the mobile device and try and browse to the IP of the machine that Burp is running on and the port that Burp's proxy listener is listening on, what happens (i.e. something like http://192.168.0.2:8080)?

Hi, I did in fact try to do that. But I get the same result. It times out.

Mehdi | Last updated: Feb 24, 2022 01:30PM UTC

Figured it out. I configured my phone to connect to a hotspot on my Linux host but the proxy configured on the iPhone was the IP address of my linux on the hotspot vlan when it should’ve been the IP on the interface that actually has access to the internet outside of the hotspot. Typically eth0… Anyway should’ve been more thorough in my debugging. Thanks for your help.

Once I configure the proxy. It seems to ignore it. The only thing that seems to go through is the captive.apple.com:80 I have tried to reset the network. Renewed the lease. Once I renewed the lease, it seems to work.
