Every failure on the GameHostCloud platform produces a deterministic error code in the form GHC-AREA-SUB-NNNN, so a problem can be identified precisely instead of guessed from a generic message. This reference lists every code with its meaning, the area of the platform it comes from, the most common causes and the concrete steps that resolve it. Provisioning codes cover capacity, region placement and image pull problems. Runtime codes cover startup failures, memory exhaustion, crash loops and mod or plugin conflicts. Network codes cover port reachability, DNS resolution and latency anomalies. File and console codes cover SFTP access, uploads and log streaming. Billing codes cover payment authorisation, balance and subscription state. When contacting support, quoting the code from the panel lets the team reproduce and fix the exact condition immediately.
