Railsapi.internal/auth/controller/callback: 404 Not Found

I have upgraded to 2.3.1 and trying to configure authentication with LDAP. I’m getting this error when trying to login. I need some help to fix it. Thank you.

Could you post the logs from Arvados controller when you try to log in?

I found that arvados-api-server was uninstalled on the controller server. It works now. Thank you.
