PageSpeed Admin on different port shows no statistics

[Daniel Raloff]

PageSpeed version: 1.12.34.3-stable

Nginx version: 1.12.2

I have the pagespeed admin set up on the same domain but on port 8000, and it seems that that is preventing the console from accessing the statistics generated on port 443.

No matter how much traffic is sent, histograms have no data, and console graphs show NaN%

I'm certain that statistics are being generated, because I can see them when I put the admin location in the port 443 server block. 

Here's the relevant config sections:

server {
  listen *:80 default_server;

  if ($ssl_protocol = "") {
    return 301 https://$host$request_uri;
  }

  location ~ "\.pagespeed\.([a-z]\.)?[a-z]{2}\.[^.]{10}\.[^.]+" {
   add_header "" "";
  }

  location ~ "^/pagespeed_static/" {
  }

  location ~ "^/ngx_pagespeed_beacon$" {
  }
}

server {
  listen *:443 ssl default_server;

  location ~ "\.pagespeed\.([a-z]\.)?[a-z]{2}\.[^.]{10}\.[^.]+" {
   add_header "" "";
  }

  location ~ "^/pagespeed_static/" {
  }

  location ~ "^/ngx_pagespeed_beacon$" {
  }
}

server {

  listen *:7999;

  pagespeed AdminPath /admin;

  if ($ssl_protocol = "") {

       return 301 https://$host:8000$request_uri;

  }

  location ~ ^/$ {

        return 301 /admin;

  }

  location ~ ^/admin {

   }

}

server {
  listen *:8000 ssl;

  pagespeed AdminPath /admin;

  location ~ ^/admin {

    }

  location ~ ^/$ {

       return 301 /admin;

  }

}

And the output of the configuration tab for some more info:

Things like setting the admin path and location blocks get duplicated due to a quirk in configuration management, but I wanted to include them here for completeness. If I move the AdminPath directive and the corresponding location block into the server block listening on 443, I see the statistics I would have hoped to see before.

Is there a configuration setting I've missed? Is this working as intended, or could it be a bug? Any help on this would be appreciated.

Thanks,

Dan
