Have you ever found yourself staring at an error message that reads “Unable to connect to host on port 57573 after 45000 ms”? If so, you’re not alone. This common problem can stop you from reaching your local server, which is a big deal if you’re trying to get work done or troubleshoot software issues.

Many things can cause this type of connection failure, but one important fact stands out: the compatibility between your browser and certain versions of Selenium—a tool many use for automating web browsers—can trigger this error.
In this blog post, I will talk about some basic and more advanced steps to fix the connection issue with port From checking that your server software is indeed running to adjusting settings in Windows or tweaking configurations in tools like XAMPP, WAMP, or even Visual Studio Code for a smoother experience with localhost connections, we’ve got it covered.

You might need to investigate settings you’ve never thought about before, like firewall permissions or network adapter options.

Understanding the Connection Issue to

Sometimes, trying to connect to feels like hitting a brick wall. This address is your own computer, and when things go wrong, it’s usually due to common problems with how your system or software is set up.

Common Causes of Connection Failures

One big reason for connection failures is trying to access a web server through the wrong port. Imagine you’re trying to get into your house, but you’re using the key for your shed.

It just won’t work. This happens online too. If Port 80 is busy with another app, like Skype or an RSS reader, you can’t use it for your webserver. You have to check which door—uh, I mean port—is open.

Another cause might be not having enough permissions to reach certain files or directories on the local web server. Think of it as trying to open a locked room in your house without the key.

On my computer, I faced this issue when Windows Firewall didn’t let me reach because it didn’t recognize my attempt as safe traffic. Adjusting firewall settings and making sure proper permissions are set can clear these roadblocks quickly.

Initial Troubleshooting Steps

First, make sure your server is awake and working properly. Give your firewall settings a quick check to keep things smooth. Dive into more tips to get you back on track—just one click away!

Verify the Server is Running

To make sure your server is active, open the task manager on your computer. Look for Apache2 or a similar web service process in the list of running applications. If you see it there, your server is up and working fine.

This step is crucial because if your server isn’t running, you can’t connect to any port, let alone

I once had a project where I needed to access localhost at this specific port but kept facing errors. After minutes of frustration, I realized I hadn’t started Apache2 through XAMPP’s control panel, which sits quietly in the system tray near Windows clock—easy to overlook! Once I hit that “Start” button next to Apache2, my connection issue vanished like magic.

Always double-check if the web service process has begun by looking for its indicator in areas like the system tray or using command line tools that confirm its status.

Check Firewall Settings

Firewalls act like gatekeepers, deciding which data can enter or leave your computer. Sometimes, these guards block the port needed for servers like XAMPP or WAMP to work properly on your Windows operating system.


It’s like having a guard that’s too strict and doesn’t let friends into your house. To fix this, open the firewall settings from the control panel—this is easy to find by searching in the start menu or using the windows key.

I had to do this myself once when I couldn’t connect my project in VS Code due to a blocked port by my firewall. After opening the firewall settings, look for an option that lets you allow specific apps through the firewall—there should be a check box next to each app listed there.

Find XAMPP or WAMP (or any server you’re using) on this list and check its box if it’s not already checked. Also, make sure networking features are allowed for private and public networks so that nothing interferes with local development tasks.

Change Apache Web Server Port in XAMPP or WAMP

Changing the Apache Web Server Port in XAMPP or WAMP is like moving your front door to a quieter street. Maybe you’ve found that port 80 is too busy, clashing with other programs on your computer.

I ran into this problem myself when trying to launch my local development environment for testing android apps and using various internet tools. It caused quite a headache until I learned how to switch ports.

First, you need to stop the Apache service if it’s running. This step ensures that when you make changes, they’re correctly applied without any conflicts. Then, dive into your server’s heart by opening the `httpd.conf` file in XAMPP or WAMP.

This file is like a map of Apache’s settings, including which doors (ports) it uses to welcome traffic (data). Here’s where the magic happens: find the lines that say “Listen 80” and “ServerName localhost:80”.

These lines are telling Apache to use port 80. Change them both to “Listen 8080” and “ServerName localhost:8080”. This moves your ‘door’ from port 80 to port 8080, reducing potential clashes with other applications.

After making these edits, save the `httpd.conf` file and restart Apache through either XAMPP or WAMP’s control panel. If things go sideways—maybe you accidentally close WAMP without stopping its services—just pull up Task Manager and check there are no lingering instances of WAMP running before you try again.

This simple tweak saved me from endless frustration while working across different operating systems and juggling tasks like usb debugging Android apps from my desktop workstation; all without having internet connectivity problems that could slow down productivity or worse—bring it offline entirely during critical moments in a production environment setup.

Restart LXSSManager Service for WSL

Press WINDOWS KEY + R to open the RUN dialog. This brings up a quick access box where you can type commands. Here, enter SERVICES.MSC and hit ENTER. This action opens the Services window on your computer, which lists all background processes and services running on your Windows system.

Look for LXSSMANAGER in this list—it’s a service that helps Windows Subsystem for Linux (WSL) work smoothly.

To restart LXSSManager, right-click on it and choose “Restart” from the menu options. Restarting this service can fix bugs and issues with WSL not connecting or working as it should.

It’s a straightforward step, but it can greatly improve how your computer talks to WSL, providing smoother operations for tasks involving multiple operating systems or when using tools like VSCode for development purposes.

Access Localhost with the Port Number

Enter LOCALHOST, a colon, and the port number into your browser’s address bar to access the local web server. For instance, if you’re working with Apache Web Server on XAMPP or WAMP and have set it to use port 8080, you would enter “LOCALHOST:8080.”.

This step is crucial when multiple services run on different ports. It ensures that the correct application responds.

I once had to switch my server from the default port 80 to 8080 because another program was using port 80. After updating my Apache configuration file from “ServerName localhost:80” to “ServerName localhost:8080,”  I could only reach my site by specifying the new port in the address bar.

Remembering this detail saves time and prevents confusion during development or troubleshooting network issues like DHCP conflicts or firewall blocks that might interfere with connections at common ports used by laptops, tablets, and other devices connecting over Wi-Fi or Ethernet interfaces in an internet-exploring setting.


Fixing connection problems at port might seem tough, but it’s doable with the right steps. First, make sure your server is on and check your firewall settings—these simple checks often solve the issue.

If not, dive a bit deeper by adjusting Apache Web Server ports or restarting LXSSManager Service for WSL users. Always remember to include the port number when accessing localhost; this small detail can make a big difference.

With patience and these troubleshooting tips, you’ll conquer those pesky connection issues in no time!
