TCP tunnel is created but connection is not establishing.

[kenilpatepy]

Error is like while making connection

TimeoutError: [WinError 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

My tcp config for nginx is like

server {
server_name tcp.example.com;

location = /favicon.ico { access_log off; log_not_found off; }

location /_ws/ {
    include proxy_params;
    proxy_pass http://localhost:4500;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";

    proxy_connect_timeout       600;
    proxy_send_timeout          600;
    proxy_read_timeout          600;
    send_timeout                600;
}

location / {

ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;

Hello,
Here's the actual Nginx configuration I am using for hosting jprq TCP:

server {
    server_name tcp.jprq.io;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /_ws/ {
        include proxy_params;
        proxy_pass http://localhost:4500;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Origin "";
        
        proxy_connect_timeout       600;
        proxy_send_timeout          600;
        proxy_read_timeout          600;
        send_timeout                600;
    }
    
    location / {
        include proxy_params;
        proxy_pass http://localhost:4500;
    }

    listen 443 ssl;
    ssl_certificate /etc/letsencrypt/live/jprq.io/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/jprq.io/privkey.pem;
}

Let me know if you need any further help.

Can you tell me cloudflare configuration because when i am trying to make connection with ip address instead of tcp.example.com it makes connection. But with host name timeout error occurs.
