so

Solution:

use HTTP as protocol, also for HTTPS.

Technical details:

These garbled characters are the head of HTTPS.

In fact, the HTTP (proxy) protocol will send a CONNECT head first, then start HTTPS handshake (for HTTPS traffic). Most proxy applications use this. But the HTTPS (proxy) protocol will start HTTPS handshake directly, thus we get the wrong head.

To avoid the problem, we may add auto-detection for these two protocols. But it need some time as we use CONNECT head to detect the remote server now.
