Release : All Clarity releases
Component : CA PPM INTEGRATIONS & INSTALLATIONS
When comparing the HAR traces, we found the request in working scenario has 2 extra headers - Sec-Fetch-Mode and Sec-Fetch-Site. These 2 headers are missing in the non-working request scenario.
While, these headers are not used or expected by the CA Clarity PPM server, according to https://www.w3.org/TR/fetch-metadata/#sec-fetch-mode-header these headers might be used by layers before applications like LB, Reverse Proxy etc, to establish trust between client and server even before passing the request to actual application.
This issue is something related to LB configuration on customer side and related to these 2 headers. The customer should work with their IT support to resolve this issue with LB/Reverse proxy config
