TLSv1.3 not accepted by server preferences

Bejal Jul 26, 2019 03:44PM UTC


I'm trying to route traffic from an app on my android through the Burp proxy. I've set up the proxy/installed the burp certificate so that traffic can come through just fine from Chrome on my phone - however when I try run other requests on the app I get this message in the Event Log

`the client supported protocol versions [TLSv1.3, (D)TLS--5.26] are not accepted by server preferences [TLS12, TLS11, TLS10, SSL30, SSL20Hello]`

For context, i've checked `select all` on Project Options > SSL Protocols and SSL Ciphers. I've also run the .jar version of burp with the latest JDK release. I'm also quite new to Burp, so I feel like I might be missing some configuration here?

Any help or resources is appreciated! :)

Have you tried using the “Use custom protocols and ciphers” setting and only using TLSv1.3?

Hi Liam, yes I have tried to do that. I've tried checking all of the options and then only checking TLSv1.3 but still to no avail

Is the application publicly accessible? If so, we’d like to do some testing to find a solution.

Same problem
Why does not Burp suppor TLS 1.3?

Anton, is the application you are having issues with publicly accessible? If so, we’d like to do some testing to find a solution.

I tested the latest facebook android app, with the same error.
Even after the so patch done.

Is it related to this?

Are you able to see TLS 1.3 in the “custom protocols and ciphers”?
