How to setup nginx multiple apps and mutiple ports with one ssl - nginx

Question

I have already deployed in HTTPS. This is my nginx.conf
server {
listen 3000 ssl;
listen [::]:3000 ssl;
server_name localhost hostname.com;
ssl_certificate ssl-bundle.crt;
ssl_certificate_key privatekey.pem;
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains";
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass http://127.0.0.1:4000/;
proxy_redirect off;
proxy_read_timeout 240s;
}
}
I want to run new app with new port on the same domain, I try to add this:
server {
listen 4000 ssl;
listen [::]:4000 ssl;
server_name localhost hostname.com;
ssl_certificate ssl-bundle.crt;
ssl_certificate_key privatekey.pem;
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains";
location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass http://127.0.0.1:8000/;
proxy_redirect off;
proxy_read_timeout 240s;
}
}
When run two app I can use https only port 3000 but can not use app on port 4000. How to config file?
