Here are the ways that the doomed error “localhost refused to connect” can be on your pc for the following reasons:

  1. It can happen when the localhost on your machine is not connected to 127.0.0.1. That could be the reason why you weren’t able to connect to your localhost from the device’s terminal. 
  2. There could be a case where the port 80 on your computer is being used by another application. 
  3. It could be a case where your computer is configured to another port instead of the default port 80. On writing localhost:80 in the terminal, it would redirect you to the port having the wrong address.
  4. You could also have a case of insufficient permissions. When you are trying to access a file in the local system but couldn’t do so because you didn’t have permission to access it.

Ways to fix localhost error

By disabling the firewall

  • A firewall is like a security shield for your computer that saves it from malicious content. 
  • It blocks suspicious contents to be accessed by you on the internet but, sometimes it may also block safe sites to be opened by you.
  • You can block your firewall for the time being when you want to run the website on the local machine.

Flushing your DNS

  • The function of the DNS cache is to store data from websites you have visited. 
  • It makes the web pages already opened in the past reload faster in the future.
  • However, if there are many records stored in DNS, it might fail to function accurately.

Connect with the correct port

  • The default port on the local machine is port number 80.
  • You’re trying to access the localhost website continuously but you figure out later that it may be connected to another port number entirely.
  • Then, you’ll have to check whether port 80 is free or not using XAMPP. XAMPP works fine on windows, mac, and Linux.

Apache is working 

  • To make your web server accessible offline, it is necessary that the apache web server runs.
  • The commands to check your apache web server will be different depending on the distribution you are using.

Verify browser settings

  • Since every browser comes with a different setup and characteristics, the fault can be in the browser settings that are not causing the error of 127.0 0.1 refused to connect.
  • For example, on entering the web address in the search bar, some browsers will take you instantly to its HTTPS equivalent.
  • It won’t work if the site has an invalid SSL certificate or none at all, you are bound to receive the “localhost refuse to connect” message.
  • The steps for making changes to the error in the chrome browser:

                 Step 1: On the address bar of your browser, type chrome://net-internals/#hsts

              Step 2: After locating “delete domain security policies”, type localhost in the blank text field.

              Step 3: Open and close the browser after doing the above steps.
