SSL Certificate - certificate_unknown - Android

[nicexavi]

Hi,

I'm trying to run the BrowserMobProxyServer with an Android device to monitor the traffic.

The problem, it's that I can't monitor the traffic that runs over HTTPS.

I've installed on my Android the certificates and it still won't work.

The BrowserMobProxyServer it's throwing me the following error:

[INFO 2019-07-09T13:07:23,528 org.littleshoot.proxy.impl.ProxyToServerConnection] (LittleProxy-0-ProxyToServerWorker-5) (HANDSHAKING) [id: 0x5528a2aa, L:0.0.0.0/0.0.0.0:57932 !

Can anyone help me, please?

@jekh @lightbody @nite23 ?

I'm using BrowserMobProxyServer version 2.1.5. I've tested with the Standalone and the embedded version. The error it's the same in both.

Thanks!

Really?

Nobody?

I'm encountering this problem now. Do you know the password for the certificate?

And which certificate should I use? I am working on Ubuntu 16.04 and Chrome.
