Nginx returning 301 when mod_zip tried - web-services

Question

I would like to download my folders as a zip from /opt directory. I have the Nginx as a webserver. I found out that mod_zip can handle such a task. I installed and configured it as stated in GitHub.
From my understanding, I created this Nginx.conf:
uwsgi_intercept_errors on;
upstream geoserver_proxy {
server 10.0.14.84:8080;
}
upstream ziplist {
server 10.0.14.84:5555;
}
# Expires map
map $sent_http_content_type $expires {
default off;
text/html epoch;
text/css max;
application/javascript max;
~image/ max;
}
server {
listen 5555;
location /reports/ {
alias /opt/geonode/;
add_header X-Archive-Files 'zip';
# this line sets the name of the zip that the user gets
add_header Content-Disposition 'attachment; filename=example.zip';
}
}
server {
listen 80 default_server;
listen [::]:80 default_server;
root /var/www/html;
index index.html index.htm index.nginx-debian.html;
server_name _;
charset utf-8;
etag on;
expires $expires;
proxy_read_timeout 600s;
# set client body size to 2M #
client_max_body_size 50000M;
location / {
etag off;
uwsgi_pass 127.0.0.1:8000;
uwsgi_read_timeout 600s;
include uwsgi_params;
}
location /static/ {
alias /opt/geonode/geonode/static_root/;
}
location /uploaded/ {
alias /opt/geonode/geonode/uploaded/;
}
location /reports/ {
alias /opt/geonode/;
# hides the header to the user
proxy_hide_header X-Archive-Files;
# I don't remember if this is needed
proxy_set_header Accept-Encoding "";
# I don't know what this means
proxy_pass_request_headers off;
# pass the request to server B
proxy_pass http://ziplist;
}
location /geoserver {
proxy_pass http://geoserver_proxy;
include proxy_params;
}
}
Unfortunately, when I try localhost/reports/folder I am getting 301 301 Moved Permanently error.
What is wrong with my config?
