NetConnection.Call.Failed: HTTP: Status 400
o report doesn't render on the screen
o no axis
Release : 20.1
Component : UIM - UMP_REPORTS
Checked Performance reports from two different locations/laptops in the UK to access a few PRD reports. No data renders and the y-axis does not refresh/display anything at all.
Portlet DEBUG mode when activated, dumps data to the portal.log but shows no errors/failures/exceptions.
Browser->F12 Developer Tools show all HTTP 200 Status codes/no errors whatsoever. Happens from any browser.
Access to and rendering of the reports worked absolutely fine from the US machines using either US/UK userid/login.
So we knew that the issue had to do with either the UK web/network response/lack of response, firewall-related blocking/filtering or VPN or ISP (BT).
Customer checked with their local resources and found that the reports worked from within the local office.
So this was either a vpn issue or local BT telecom issue. They have suggested that they request a citrix desktop on site to be able to run reports.
