How can I route to multiple NodeJS applications using Nginx?

Question

I have 2 NodeJS applications running locally on port 3000 and 3001. I'm trying to route to them individually by using my_ip/tilbudsfinneren for one of them, and my_ip/hms for the other one.

My sites-available file looks like this:

server {
 listen 80;
 listen [::]:80;
 root /var/www/my_ip/html;
 index index.html index.htm index.nginx-debian.html;
 server_name my_ip www.my_ip;
 location /tilbudsfinneren {
 proxy_pass http://localhost:3000;
 proxy_http_version 1.1;
 proxy_set_header Upgrade $http_upgrade;
 proxy_set_header Connection 'upgrade';
 proxy_set_header Host $host;
 proxy_cache_bypass $http_upgrade;
 }
 location /hms {
 proxy_pass http://localhost:3001;
 proxy_http_version 1.1;
 proxy_set_header Upgrade $http_upgrade;
 proxy_set_header Connection 'upgrade';
 proxy_set_header Host $host;
 proxy_cache_bypass $http_upgrade;
 }
}

Whenever I try to reach my_ip/hms or my_ip/hms/ping it does not reach the NodeJS application, I get get "Cannot GET /hms". Is there an issue with my nginx configuration, or is there maybe something else wrong?

If you want to serve both apps as reverse proxy you must use rewrite methods in both locations.

server {
 listen 80;
 index index.html index.htm index.nginx-debian.html;
 location /tilbudsfinneren/ {
 rewrite ^/tilbudsfinneren/(.*)$ /1ドル break;
 proxy_pass http://localhost:3000;
 #other config... 
 }
 location /hms/ {
 rewrite ^/hms/(.*)$ /1ドル break;
 proxy_pass http://localhost:3001;
 }
}
