When faced with the 'Can't connect to proxy server Windows 10' error, it's essential to understand the root of the problem. This guide will explore the potential causes, from misconfigured proxy settings to unstable internet connections, and provide you with practical solutions to get you back online in no time.

Causes of The Problem

There are several factors that could lead to the "can't connect to the proxy server" error message on Windows 10. Here's a breakdown of some of the most common causes:

Firewall or Internet Filter Blocking the Connection

Firewalls and internet filters act as security barriers to prevent unauthorized access or to comply with internet usage policies. They can block specific types of traffic or websites, which could include the connection to a proxy server.

Incorrect Proxy Settings

Proxy servers act as intermediaries between your computer and the internet. Incorrect proxy settings, such as entering the wrong IP address, port number, or failing to provide the necessary authentication details (username and password), can hinder the connection. 

Outdated Network Drivers

Network drivers are software components that enable communication between the computer's operating system and its network hardware. Outdated or incompatible network drivers can cause various connectivity issues, including problems connecting to a proxy server.

Malware or Virus Infection

Malware and viruses can disrupt the computer's internet connection by modifying proxy settings or blocking the connection altogether. This can prevent users from accessing online resources to remove the infection.
