SSH Remote fails to connect when there is a jump server

Does this issue occur when all extensions are disabled?: No

Remote-SSH: v0.106.5

I've tried both stable and nightly version of VSCode and Remote-SSH.

Stable VSCode + Stable Remote-SSH: OK
Nightly VSCode + Nightly Remote-SSH: Buggy
Nightly VSCode + Stable Remote-SSH: Buggy

So I believe it only relates to vscode itself.

Steps to Reproduce:

Configure sshd config:


Host host1
HostName *
Port 22
IdentityFile *
ProxyCommand D:/bin/cloudflared access ssh --hostname %h

Host host2 ProxyJump host1 HostName 192.168.254.203 Port 22 IdentityFile *

2. ssh to host2

VSCode Insider can connect at first. But when opening a terminal, the connection lost.
