I'm having trouble following the docu to set up a Linux Identity server behind a LAG. Following the document at the end I receive the famous 'unable to authenticate'.

First question I have:
If I change the port in the Base URL in the Identity Servers to 443 and refresh/restart both Identity server and LAG should a wget https://<ip of identity server:443/nidp/idff/metadata be possible? If I change the port I still receive the metadata on port 8843 is this correct?
