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.
