i have my domain and hosting service in hostinger. i also have created subdomain and it’s private folder and in that folder i have uploaded node app but i don’t know how to run that app on api.mydomain.com (my subdomain).

I started a server on port 4000 using ssh access but it didn’t work.

searched online 100 time even asked multiple AIs but couldn’t solve it any expert to help me ?

i wanted to just upload my node app on subdomain folder run it on a port and see results on subdomain.
