FSTL150 - Failed to Create the Fastly ACL Entry
Agent error code #FSTL150 indicates Fastly refused to add the entry for a granted address, so the user has not been allowed through.
An address the ACL already holds is not an error: Knocknoc treats a duplicate as a successful grant. A full ACL reports #FSTL153 instead.
Common causes include:
- The token can read the service but cannot write ACL entries (see #FSTL002)
- The ACL was deleted between the lookup and the write (see #FSTL101)
- A transient API failure
Steps to Resolve
- Confirm the API token has write access to the service
- Confirm the ACL still exists on the service's active version
- Once the cause is fixed, have the user request access again. A grant that fails on its first attempt is reported as failed and is not re-applied on its own
