Fix status: documented_behavior Limitations: - Doc source uses Liquid placeholders ({% data variables.product.prodname_vscode_shortname %}); verbatim check done against a copy with the placeholder rendered as 'VS Code'. - Same surface error has several unrelated causes; the Remote-SSH output log is needed to pick one. - Not reproduced in this session. Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/microsoft/vscode-docs/0db25bd8e8e2efc22ba752e44451e69c599058c3/docs/remote/troubleshooting.md (official_docs, 2026-09-27, documented_behavior): Troubleshooting doc says 'Remote-SSH: Kill VS Code Server on Host' removes the server and fixes errors such as 'The VS Code Server failed to start'; also lists showLoginTerminal, /tmp noexec, shell-switching in .bash_profile and proxy/internet as causes of hangs/failures.
