The Troubleshooting Guide for “The Remote Server is not a Known TCP/IP Host” Error

Dear Dev, if you have come across the “The remote server is not a known TCP/IP host” error message, don’t worry. This error is a common issue faced by web developers and network administrators. In this article, we will provide you with a comprehensive guide on how to troubleshoot this error and fix it.

What is the “The Remote Server is not a Known TCP/IP Host” Error?

Before diving into the troubleshooting guide, let’s first understand what the “The remote server is not a known TCP/IP host” error means. This error message appears when your computer or server is unable to establish a connection to a remote server or device via TCP/IP protocol.

When you try to connect to a remote server or device, the TCP/IP protocol verifies the existence of the remote host and checks if it is available for connection. If the protocol cannot locate the remote server, the error message “The remote server is not a known TCP/IP host” appears. This error can occur due to various reasons, including incorrect DNS settings, network configuration, or firewall settings.

Common Causes of the “The Remote Server is not a Known TCP/IP Host” Error

Before we proceed with the troubleshooting guide, let’s take a look at the common causes of this error:

How to Fix the “The Remote Server is not a Known TCP/IP Host” Error?

Check your DNS settings

The first step in troubleshooting this error is to check your DNS settings. DNS translates domain names into IP addresses, which are then used to establish connections with remote servers. If your DNS settings are incorrect, your computer will be unable to resolve the IP addresses of remote servers.

To check your DNS settings, follow these steps:

1. Open the Command Prompt on your computer.
2. Type “ipconfig /all” and press Enter.
3. Look for the “DNS Servers” section and check if the IP addresses are correct.

If the DNS settings are incorrect, you can update them manually or contact your network administrator to fix the issue.

Check your network configuration

If your DNS settings are correct, the next step is to check your network configuration. Misconfigured subnet masks or incorrect IP addresses can cause the “The remote server is not a known TCP/IP host” error.

To check your network configuration, follow these steps:

1. Open the Command Prompt on your computer.
2. Type “ipconfig /all” and press Enter.
3. Check the “IPv4 Address” and “Subnet Mask” sections to ensure they are correct.
4. If they are incorrect, you can update them manually or contact your network administrator to fix the issue.

Check your firewall settings

If your DNS settings and network configuration are correct, the next step is to check your firewall settings. Firewalls can block incoming and outgoing connections, which can result in this error.

To check your firewall settings, follow these steps:

1. Open the Windows Defender Firewall on your computer.
2. Click on “Allow an app or feature through Windows Defender Firewall.”
3. Ensure that the programs you are trying to connect to are allowed through the firewall.
