How to Fix Connection Refused is the Server Running on Host Error?

Here are some effective solutions that can help you fix the “Connection refused is the server running on host” error:

Solution 1: Check the Server Availability

The first step to fixing this error is to check whether the server is running or not. You can try to ping the server or use a simple tool like ‘telnet’ to check its availability.

Here’s how you can use telnet on Windows:

1. Press the Windows key + R to open the Run dialogue box.
2. Type ‘cmd’ and press Enter to open the Command Prompt.
3. Type ‘telnet’ followed by the IP address or hostname and the port number of the server you want to connect to. For example, telnet 192.168.0.1 80.
4. If the server is running, you will get a message saying “Connected to [hostname].”.
5. If you receive a connection refused error, it means that the server is either not running or not accepting connections on that particular port.

Here’s how you can use telnet on MAC or Linux:

1. Open the Terminal.
2. Type ‘telnet’ followed by the IP address or hostname and port number of the server you want to connect to. For example, telnet 192.168.0.1 80.
3. If the server is running, you will get a message saying “Connected to [hostname].”.
4. If you receive a connection refused error, it means that the server is either not running or not accepting connections on that particular port.

Solution 2: Check Firewall and Anti-Virus Settings

Firewall and antivirus programs are designed to protect your system from external threats. However, sometimes they can block the server ports and prevent you from establishing a connection.

You can check the firewall and antivirus settings to see if they are blocking the ports. You can temporarily disable the firewall and antivirus software and then try to connect with the server. If the connection is established, it means that the firewall or antivirus software was blocking the port. You can then re-enable the software and configure it to allow connections on that specific port.

Solution 3: Check Network Settings

If the firewall and antivirus settings are not the cause of the error, you can check the network settings on your device or server. Ensure that the IP address, gateway, and DNS settings are configured correctly. Make sure that the network connection is active and functional.

Solution 4: Restart the Server

If all the above solutions do not work, you can try restarting the server. Sometimes, a simple restart can fix technical issues and enable you to connect to the server.
