Description

Type: Bug

Just open Remote-SSH connection to the server, which is Ubuntu 22.04.

UPD. Found that problem is related to AddressFamily inet6 in my ~/.ssh/config

Host *.yandex.net
  AddressFamily inet6

If I disable it, all starts to work fine. Looks like a bug somewhere in extension or VSCode.

Research direction

Reproduce the failure with AddressFamily inet6 in ~/.ssh/config and a Remote-SSH connection to the Ubuntu server. Start by inspecting the tunnel creation path reported in the extension.js stack trace. Done means the local forwarding tunnel is established successfully without the bind error or resolver timeout.
