When a job fails, the error message includes an error code that tells you what went wrong and whether retrying will help.

​
Error types

  • Permanent errors — The problem won’t resolve by retrying. You need to fix the underlying issue. Credits are automatically refunded.
  • Temporary errors — A transient issue that usually resolves by clicking Retry. If the error persists after 2–3 retries, contact support.
These errors indicate a problem with the input. Credits are automatically refunded.

​
Automatic refunds

All failed jobs — whether permanent or temporary errors — are automatically refunded. You don’t need to contact support. Refunds appear immediately in your credit history.

​
Checkpoint-based retry

When you retry a job, Neolli resumes from the last checkpoint rather than starting over. This means:
  • Faster retries — Completed work is preserved
  • Lower cost — You’re only charged for work that actually completes
  • Better success rate — Transient issues typically don’t recur on retry
See A Job Failed for more details on the retry process.
