3732553 - SAC Stories Fail to Load with “Failed to Fetch Data” or “Cannot Reach the Remote System” on Live Connection - SAP Analytics Cloud

Symptom

  • SAC stories are not getting executed.
  • Error shown in story: “Failed to fetch data.”
  • Error shown in some cases: “Cannot reach the remote system. It may be offline.”
  • Browser traces show HTTP 404 on GET /sap/public/bw/ina/storageaccess/request.html.
  • Browser traces show HTTP 403 Forbidden on POST /sap/bw/ina/GetResponse.
  • Some stories on the same backend work, while others fail (including when switching the live connection target).

Environment

  • SAP Analytics Cloud 2026.2.6 -> 2026.2.10.

Reproducing the Issue

  1. Open a story that uses a live data connection.
  2. Provide required variables/filters for the underlying model.
  3. Run or refresh the story.
  4. Observe the message “Failed to fetch data.” In developer tools, network calls may show 403/404 on BW INA endpoints.

Cause

The customer's AWS WAF was blocking requests containing /sap/bw on the Fiori Load Balancer, causing legitimate traffic to be denied.

Resolution

The cusotmer's basis team added an exception rule in AWS WAF to allow /sap/bw requests. After the exception was applied, the functionality resumed working normally.
