203003 - GCP API Connection Timed Out

Agent error code #203003 indicates that the agent's request to the GCP Compute Engine API timed out before receiving a response. This can be a network-level timeout or an HTTP 408/504 response from the API.

This error is distinct from general connection failures (#203000). Error #203003 specifically indicates that a connection was initiated but did not complete within the expected time.

Common causes include:

• Network latency or congestion between the agent and the GCP API
• A firewall or proxy is silently dropping outbound connections
• The GCP API is under heavy load or experiencing degraded performance
• DNS resolution is slow or intermittent

Steps to Resolve

Check Network Path

1. Verify the agent host has stable connectivity to compute.googleapis.com
2. Test latency with: curl -o /dev/null -w "%{time_total}" https://compute.googleapis.com/compute/v1/
3. Look for packet loss or high latency using ping or traceroute to GCP API endpoints

Check for Network Interference

1. If the agent is behind a corporate firewall or proxy, ensure it allows long-lived HTTPS connections to GCP
2. Check that no connection timeout policies are set lower than the API response time
3. Verify that IDS/IPS systems are not interfering with HTTPS traffic to GCP

Check GCP API Status

1. Visit the Google Cloud Status Dashboard to check for ongoing incidents
2. If the issue is intermittent, it may resolve on its own as the agent automatically retries operations
