Description

Hi, thanks for you excellant product!

I'm trying to capture traffic from Android application. Here is my procedures:

Root the android device
install the proxyman cert to system CA
install Proxydroid app to phone
set Proxydroid to transfer the traffic to [ProxymanIp]:9090
open android chrome and then check capture on Proxyman

We can see that all HTTPS capture cannot get domain but only ip. It causes that proxyman cannot capture HTTPS correctly.

However, other alternative proxy software on Windows such as Fiddler Classic and Mitmproxy can handle this correctly (Fiddler need additional settings). As far as I know, they obtain the server name indicator from the client's TLS handshake instead of using the HOST field from the CONNECT. (Reference https://groups.google.com/g/httpfiddler/c/hvsDR14j1Lg/m/P02zBzIYCE4J)

It seems there is an similar issue. But I'm not sure. Proxyman does not use SNI when generating certificates for use with SSL Proxying · Issue #1581 · ProxymanApp/Proxyman

Therefore, it will be wonderful if you can fix this issue.

Steps to Reproduce

Root the android device
install the Proxyman cert to android system CA
install Proxydroid app to phone
set Proxydroid to transfer the traffic to <Proxyman's IP>:9090
open android chrome and then check capture on Proxyman

Current Behavior

Expected Behavior

Environment

App version: e.g Proxyman Windows 2.2.0
Windows version: 22H2
