Mon, 26 Oct 2026 03:17:39 +0000

[Cline] MCP: a remote server restart/deploy wedges the session — the client never re-initializes on a 404 `Session not found` (sdk/packages/core)

Workaround (quoted from issue body): The only workaround is restarting Cline (in the CLI/TUI, restarting the hub daemon, which is what actually owns the connection).
