FSTL050 - Failed to Read the Fastly Service

Agent error code #FSTL050 indicates the agent could not read the configured Fastly service. It reads the service to find the active version, which is where the ACL lives.

Common causes include:

  • The Service ID is wrong (see also #FSTL051)
  • The token cannot read this service (see also #FSTL002)
  • A transient API failure

Steps to Resolve

  1. Confirm the Service ID matches the ID shown on the service's page in the Fastly control panel
  2. Confirm the token's scope covers that service
  3. Run Validate connection in the Knoc wizard, which reports which of the two it is
