Autodesk Login - DNS Gateway Settings

I have operated DNS servers for Shotgun using haproxy and named service.
However, Autodesk authentication procedures have not been working properly since the migration to Shotgrid.

When I try to log in to Shotgrid, certificate errors occur intermittently as shown below.

I have a problem in these urls.

It’s my config files.

Could you help me set up the DNS service?
