This solution worked for me:
location ^~ /blog {
client_max_body_size 10G; # Required for uploading large files
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_pass http://127.0.0.1:2368;
}
Note in config.production.json file:
replace "url":"http://localhost:2368/"
with
"url": "https://yourapp.com/blog",
