Opening the access port

Create a proxy from port

- localhost:8332 to port 8233 for bitcoind rpc

Setting up a proxy on caddy

apt update

apt install caddy

configuring caddy for proxy

8332 to port 8233 for external network

nano /etc/caddy/Caddyfile

/etc/caddy/Caddyfile

:8233 {
  handle_path /* {
    reverse_proxy 127.0.0.1:8332
  }
  respond 404
}

launch caddy

systemctl enable --now caddy

or restart if necessary

systemctl restart caddy
