Firewalls and proxies are both elements of cybersecurity in any network. Firewalls could prevent phony access to your computer and personal data by blocking suspicious ports and programs, while proxies conceal the user’s actual IP address to hide your activity from the rest of the Internet.
The ERR_CONNECTION_REFUSED error is usually caused on the server end, rather than having to do with your attempt at connection. It’s typically a mild issue, and can just be the result of incorrect firewall or proxy server settings. Nevertheless, it can also suggest that something more important has gone wrong, for example, a hacker attack, or unexpected downtime. An unstable internet connection can also be the cause.
Urging you to Check Proxy And Firewall, this prompt lets you know that something is not working right, but without giving further information. This means it’s up to you to find and possibly fix the root problem.

You can check the relevant details in the opening window.
You can also check proxy settings or, if necessary, create a proxy server on your Android device.
A firewall gives you protection, a proxy server gives you anonymity. Although they are both effective security solutions, you can always get the best of the two worlds by using a good VPN.
Without a proxy, your device connects straight to the internet to access any given service for you. With a proxy, however, it will establish a connection through a separate server, the proxy, that sits between your device and the internet.
You can always check if you are using a proxy by checking your IP Address. If your IP address is anything other than what it used to read, you have successfully set up a proxy on your iPhone. Simply look up “what's my ip address” and you’ll see several websites that read and show your IP instantly.
The proxy option is typically set to Off by default, so your device won’t use any intermediary when connected to the internet. If you need to bypass online censorship or leave no trace of your activities over the internet, you can set up a proxy server for your connection.
You can check your proxy very quickly by clicking Start, and then Run, typing “cmd”, and finally clicking on OK. At the command prompt, type “netsh winhttp show proxy”, and then hit ENTER. Your proxy settings will appear shortly.
