FSTL051 - Fastly Service Not Found

Agent error code #FSTL051 indicates Fastly answered HTTP 404 for the configured service.

Common causes include:

  • The Service ID has a typo, or a service name was entered instead of its ID
  • The service was deleted
  • The token belongs to a different Fastly account

Steps to Resolve

  1. In the Fastly control panel, open the service and copy the Service ID from its page (around 22 letters and digits, not the service name)
  2. Paste it into the Knoc's Service ID field and save
  3. Confirm the API token belongs to the same Fastly account as the service
