Hi,

I have been using the Pre-Master-Secret key to decode TLS and HTTPS traffic for several years. I set the SSLKEYLOGFILE environment variable under Windows for this purpose. However, about three months ago, it became unreliable and eventually stopped working almost entirely on my local machine. I started a virtual machine that I hadn't used for some time, and I was able to decode HTTPS traffic with Wireshark, but after Chrome updated itself in a few mintues later, it failed to decode any traffic. My Wireshark version is 4.2.6. I reproduced the issue on two machines.

Has anyone else experienced this issue?

Okay, I went to Windows' Internet Properties>Advanced>Use TLS 1.3, and unchecked it and restart Chrome. It seems if I don't use TLS 1.3, it could decode it.

But still why TLS 1.3 does not work?
