GetFloatingIP: fetching floating IP (%s) failed: %v

Error message

GetFloatingIP: fetching floating IP (%s) failed: %v

What it means

getL3FloatingIP wraps the l3floatingip.Get Extract failure when fetching a Neutron layer-3 floating IP by ID. It fires when the Neutron API call fails (not found, auth, network) and is retried with backoff before surfacing.

Solutions

1. Verify the floating IP ID exists in the project
2. Check Neutron API credentials and connectivity
3. Retry; the operation already runs inside RetryWithBackoff
