Bitcoind rpc and nginx

Hello,

I'm writing to developers who have already worked with bitcoind and rpc calls.

Indeed, after launching my pruned node,

I try to make local calls (command line) with the test identifiers, it works, I get a result (127.0.0.1:8332).

When I try to open a port with the ip of my vps, to display the interface of 127.0.0.1:8332, I get a timeout, I don't understand, it's one of the first times I've worked with this cryptocurrency.

Edit: I mean, this cryptocurrency have public 'gui' json interface ? like read .json file in browser ?

Thanks for any help

basically, its the scheme : custom_app -> vps_ip:vps_custom_port -> 127.0.0.1:8332
There is one address for wallet ? another for network ?

nginx conf:

upstream bitcoin_node { server 127.0.0.1:8332; } server { listen some_port_on_vps_ip; server_name _; access_log off; location u/blackhole { return 444;} location / { proxy_pass http://bitcoin_node; } }
