🔧 Issue Summary¶

mcp.call2arm.com への接続で404エラーが発生していた問題を修復しました。

🔍 Root Cause Analysis¶

問題: nginx-proxy コンテナの設定が古いIPアドレスを参照

• 設定値: 192.168.208.7:3001 (旧アドレス)
• 実際値: 192.168.208.17:3000 (新MCPサーバー)

🛠️ Technical Resolution¶

1. 環境診断¶

# MCPコンテナ確認
docker ps | grep mcp
# → mcp-gateway (192.168.208.17:3000) 動作中

# Nginxプロキシ確認  
docker ps | grep nginx
# → nginx-proxy が 80/443 ポートで動作

# 設定確認
docker exec nginx-proxy cat /etc/nginx/conf.d/mcp.call2arm.conf
# → 古いIP参照を発見

2. 設定修復¶

# バックアップ作成
cp /root/nginx-proxy/conf.d/mcp.call2arm.conf /root/nginx-proxy/conf.d/mcp.call2arm.conf.backup-20250607-144105

# IP修正
sed -i 's|proxy_pass http://192.168.208.7:3001|proxy_pass http://192.168.208.17:3000|g' /root/nginx-proxy/conf.d/mcp.call2arm.conf
sed -i 's|proxy_pass http://192.168.208.7:3001/health|proxy_pass http://192.168.208.17:3000/health|g' /root/nginx-proxy/conf.d/mcp.call2arm.conf

# 構文テスト＆リロード
docker exec nginx-proxy nginx -t
docker exec nginx-proxy nginx -s reload
