reactjs - Express API backend receiving requests but not responding, Nginx -


i have front end reactjs being served nginx. shown here:

server {     listen 80 default_server;     server_name website.*  www.website.*;     root /home/developer/website/frontend/build;      location / {         try_files  $uri /index.html;     }      location /api {        proxy_set_header x-real-ip $remote_addr;        proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;        proxy_pass http://127.0.0.1:4000;     }  }

additionally, have second express app receiving requests @ 127.0.0.1:4000. front end calls fetch 'api/something' , express app receives , handles not respond, client side errors 504 (gateway time-out). ideas?

you missing upstream server directive. try this

upstream api {     server 127.0.0.1:4000; }  # remove www url server {     listen 80;     server_name www.website.com;     return 301 $scheme://website.com$request_uri; }  server {     listen 0.0.0.0:80;     server_name website.com website;     error_log  /var/log/nginx/website.com-error.log error;     access_log /var/log/nginx/website.log;      # pass request node.js server correct headers     location /api/ {         proxy_pass http://api/;         proxy_ignore_headers x-accel-expires expires cache-control;         proxy_ignore_headers set-cookie;         proxy_hide_header set-cookie;         proxy_set_header x-real-ip $remote_addr;         proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;         proxy_set_header host $http_host;         proxy_redirect off;         proxy_set_header x-nginx-proxy true;     } }

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
