当服务器在 Ubuntu 18.04 上运行时，如何解决 Windows 10 中的 google chrome“无法加载资源：net::ERR_CONNECTION_REFUSED”问题？

Question

I am trying to run this project on Ubuntu 18.04 server. I am running both server and client on this machine. Then from windows 10 with port 9000 I am getting access to client in my chrome browser at http://localhost:8000/#/

The browser loads the project but the problem is I can't log into the website with trusted account and some other data do not get loaded . When I see browser console I see an error message saying:

Failed to load resource: net::ERR_CONNECTION_REFUSED

This is the server setting:

This is the client setting and putty setting to connect to client.

VPN has been used to connect to server via PuTTY .

The error message in browser:

Could anyone shed some light on this issue? Is it related to windows 10 or VPN or some other issues? I followed some steps from here https://www.ionos.com/digitalguide/hosting/technical-matters/err-connection-reset/

By default, the Flask development environment uses 127.0.0.1 (localhost), which restricts access to process on the same host (except for VMs/containers, which aren't a factor here).

To access Flask from outside of localhost (eg, from your Windows 10 machine), use the IP address 0.0.0.0. (You can pass it to run() , or via a command line option of the flask command.

However, do note the warnings about (not) using the development environment for production use.
