Hi Alteryx
Site "https://help.alteryx.com/" do not have valide CA chain. after 2023 Oct 12th renewal , the issue is there.
To make things worse, it appears to be shutdown or generally unavailable over the past several weekends.
@Yongcan I just got a message from Alteryx Support - everything was moved into a different site. Try going here: https://help.alteryx.com/current/en/server.html then navigating to where you need to go.
