Problem Description
My Zeabur server in the Aliyun Singapore region intermittently shows as offline, even though the virtual machine itself is still running. This prevents access to any projects and services on the server.

Diagnostic Information
Ruled Out
- ✅ Insufficient resources - Previous metrics showed normal CPU/memory usage

- ✅ Disk space - Disk usage is normal
Possible Causes
- ❓ Zeabur monitoring agent connection failure
