Xenforo I created my own static/cdn sub domain, now I got problems with xenforo attachments

Here's my latest config:

Code:

server {
    listen 80;
    server_name static.phcorner.net;

    # ngx_pagespeed & ngx_pagespeed handler
    include /usr/local/nginx/conf/pagespeed_phcorner.conf;
    include /usr/local/nginx/conf/pagespeedhandler.conf;
    include /usr/local/nginx/conf/pagespeedstatslog.conf;

    log_not_found off;
    error_log off;
    root /home/nginx/domains/phcorner.net/public;

    location / {
        if ($request_filename ~ "\.(css|js|jpg|jpeg|gif|ico|png|bmp|pict|csv|doc|pdf|pls|ppt|tif|tiff|eps|ejs|swf|midi|mid|ttf|eot|woff|otf|svg|svgz|webp|docx|xlsx|xls|pptx|ps|class|jar)$") {
                add_header Cache-Control "public, must-revalidate, proxy-revalidate";
        access_log off;
        expires 30d;
        break;
                }
        return 301 http://www.phcorner.net$request_uri;
        }
}

But, XenForo attachment not working now
Any advice? Thanks!

All file attachment downloaded with "download" file name without extension.

 

It was something to do with this addon: XAR - Attachment | XenForo Community and my latest changes static domain Pinoy Internet and Technology Forums
That addon is working fine and pagespeed.
This problem only happens when I implement static cdn.

 

Very useful!
This one solve my problem
I thought it's not about pagespeed
