PuTTy is a free and open-source terminal program that allows administrators to connect to a remote server through SSH. This modest yet dependable tool can also be used to securely transfer data using SCP and SFTP.

PuTTy is not a foreign notion to you if you work in IT or have your own set of servers that need to be connected. The Putty Fatal Error, on the other hand, is a strange concept.

One of the most common PuTTY-related issues is “Network error: connection refused,” which you may encounter while using Putty. When you try to connect to a remote server for the first or 100th time, the error appears.

I’ve had my fair share of PuTTy troubles, but most of the time, the errors are caused by minor but inconspicuous faults.

This article will assist you in resolving the connection rejected error if you are trying to diagnose it.

In this post, we have listed all the possible methods to PuTTy connection refused error. Make sure you try each one of them a try until the problem is fixed.

What causes Network error: Connection Refused errors?

The error can appear for a variety of reasons. The following is a list of some of them.

  • The message “Network error: connection refused” may appear to users. error.
  • If the application tries to use services that the server does not provide or support.
  • If the application attempts to connect to a telnet server that the server does not support.
  • If your router prevents you from connecting due to security concerns.
  • If the server does not support the system administrator’s default port for PuTTy.

These are some of the most typical causes of PuTTy’s connection rejected error. The following are some common remedies to the problem that you can try.

How to fix Network Error: Connection Refused errors

Fix 1: Contact the system/network administrator

If you are not a system administrator, you should begin by contacting your system administrator.

System administrators may occasionally change some router permissions if they observe an unknown device attempting to connect or for other security reasons.

If this is the case, you can quickly remedy the problem by contacting the system administrator before attempting to resolve it yourself.

Fix 2: Check if SSH connection is enabled

If SSH is disabled on the device to which you are attempting to connect, the network error – connection rejected problem may display.

If you’re using a Raspberry Pi to connect to your PC, for example, check sure ssh is enabled in the setup. Here’s how to go about it.

Navigate to Configuration > Interfaces > ssh. Enable the service and try again.

The settings may vary depending on the device, but the end result should be a functional network connection via PuTTy.

Fix 3: Check if your domain records points to the server

The problem can arise if you are working with a new server and a new domain because the DNS server address in the domain settings is wrong. Using the name server, every domain registrar allows you to point your domain to third-party hosting provider.

You can get a network error: connection rejected error if you merely installed a server and did not update the name server.

Log into your domain name provider’s control panel and verify the name server settings to see if the name servers are pointing to your hosting provider.

Fix 4: Check for Blacklisted and Whitelisted IP Address in the server

For security concerns, the system administrator may only allow connections from computers that have a known IP address and are whitelisted in the configuration file.

If your ISP’s IP address has changed, or if you are new to the position, you will most likely need to request an exception from the network administrator.

The same thing can happen if your IP address is unintentionally banned by the network administrator.

Therefore, for both cases, check with your network administrator to see if they can assist you in resolving the problem.

Fix 5: Disable Firewall

If you’re using Windows, the Windows Security firewall or your anti-virus software and network protection feature in Windows may block incoming connections, resulting in a connection rejected error.

To investigate if the connection rejected error can be resolved, briefly disable the firewall. If this is the case, you may need to adjust the firewall settings to entirely resolve the issue.

Disable Firewall in Windows Security

  • Choose Start and then Settings.
  • Navigate to Update and Security > Windows Security.

  • Go to Firewall and network protection.

  • Choose preferred network type (Public, Private or  Domain Network) and disable Windows Defender Firewall.

Disable Anti-virus Firewall

If you have a third-party anti-virus product installed, you may need to disable the firewall it provides. The firewall can be turned off in the anti-virus settings.

Now try connecting with PuTTy. If the connection is successful, you’ll need to adjust your Firewall settings to resolve the issue.

Other Fixes

If none of the above solutions worked, try restarting the SSH server or rebooting the servers.

If your server was set up by someone else, it’s possible that the default port was moved for their convenience. To gain a better picture of the ports, contact and request the configuration nodes.

Contact support if you’re utilizing a fully managed server. If the problem is caused by the hosting provider, the system administrator will resolve it.

Last but not least, try using additional options to Putty, such as different SH terminals, in case you run across a problem that is unique to PuTTY.
