socket.io can't connect when clients are on different wifi (ip address) on my self-configured ubuntu nginx server, but works perfectly fine on a pre-configured heroku server
this is my nginx config
upstream dirtyfinger {
ip_hash;
server localhost:3000;
server localhost:3001;
server localhost:3002;
server localhost:3003;
}
server {
listen 80;
location / {
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass "http://dirtyfinger/";
}
}
