Hi,
We got this update in product page.
CA Network Flow Analysis R9.3.7
Product Advisory
Date: August 2017
To: CA Network Flow Analysis Customers
From: The CA Technologies Network Flow Analysis Product Team
Subject: Product Advisory for CA Network Flow Analysis 9.3.7
CA always works diligently to deliver quality software to our customers. During a given instance of our testing, we found an issue with the recently released NFA 9.3.7, so it has been temporarily disabled for download until the issue is fixed. The issue has been given our highest priority and we want to assure you of our best efforts to resolve the issue in a timely fashion. Until CA informs you of our resolution of the issue, we request that you defer your plans to upgrade to NFA 9.3.7. We are sorry for any inconvenience this may have caused you.
We already implemented NFA 9.3.7 on 26th July.
It is working fine till now but if something happen, please let me know the rollback scenario???
As you mentioned above the issue "403-Forbidden" error is temporary but its not, as we are still facing the issue since morning.
