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;
