Troubleshooting

Troubleshooting guides help you diagnose and resolve common problems with your Quake AI workloads. Each guide follows a symptom-first structure: start with what you observe, narrow down the cause, and apply a targeted fix.

When something goes wrong, follow this general diagnostic pattern:

  1. Identify the symptom: what exactly is failing? An SSH connection timeout, an API error code, an instance stuck in a build state?
  2. Check recent changes: did you modify a security group, rotate credentials, resize an instance, or update a configuration?
  3. Isolate the layer: is the problem at the network level (security groups, floating IPs), the instance level (OS, application), or the platform level (API errors, quota limits)?
  4. Gather evidence: collect logs, error messages, and resource status before making changes. Use openstack server show, openstack console log show, and instance system logs.
  5. Apply and verify: make one change at a time and verify whether it resolves the issue before proceeding.

Instance stuck in BUILDWait 5 minutes; if still building, check quota limitsInstance lifecycle
API returns 401 UnauthorizedRe-source your openrc.sh; token may have expiredAuth token diagnostics
Object upload fails with 403Verify EC2 credentials (not app credentials) are validObject storage access
Instance has no networkCheck that the instance is attached to a network and the subnet has DHCP enabledInstance connectivity
