/auth returning 200, but looping back to /login

From what i'm seeing, my protected resource is correctly redirecting to the login form, but i'm not sure why i can't seem to get the resource to register the 200 /auth response:

from that GET response in the log, i'm thinking that the following should catch that 200 and allow the access to proceed to the resource:

auth_request /auth;
error_page 401 = /login;

The first oddity that jumps out is that it seems like there are a number of requests going through with the same timestamp; I wouldn't expect multiple calls over the same second.

The experience is that if you try to access the protected resource, you're redirected to the login form. then, upon submitting, i'm dropped back onto the login form.

I get the exact same form, without error or help message, regardless of correct credentials, invalid username, or invalid password.


I can use the test page successfully:
accessing http://dns:9000/auth
returns:
Hello, world! Requested URL: /auth
