Bug

Telegram plugin stops delivering inbound notifications/claude/channel after opening a new terminal/session. Works on first install only.

Steps to reproduce

1. Install telegram plugin, pair, send messages — works
2. Close terminal, open new session
3. Send message via Telegram — never arrives in Claude Code

Diagnosis

• Bot token valid (getMe OK)
• Polling active (TCP ESTAB to 149.154.166.110:443)
• getUpdates via curl returns messages correctly
• Running server.ts manually with open stdin: notifications emitted correctly on stdout as JSON-RPC
• MCP tool calls (reply, react) work fine — only inbound direction is broken
• Tested with both bypassPermissions and allowEdits modes — same result

Environment

• Claude Code v2.1.87
• Plugin: telegram@claude-plugins-official v0.0.4
• OS: Ubuntu Linux 5.15.0-171-generic
• Runtime: Bun
