Description

Type: Bug

  1. Setup remote and store it in ssh config file
  2. Modify Host Alias (as recommended by documentation)
    • HostName remains unmodified
  3. Connect to Host

Expected behaviour: connection goes through and I am prompted to select a working directory

Actual behavior: connection times out, even though the output of the extension shows the server's welcome message. Connection goes through if the default Host alias is used

Extension version: 0.115.0
VS Code version: Code 1.95.0 (912bb683695358a54ae0c670461738984cbb5b95, 2024-10-28T20:16:24.561Z)

Research direction

Reproduce the connection using an SSH config entry whose Host alias differs from HostName, then inspect the Remote-SSH extension output around the timeout. The issue is resolved when the aliased host connects successfully and prompts for a working directory, as the default Host alias does.
