err_proxy_connection_failed error in Google Chrome

Internet browsing can sometimes be frustrating, primarily when a message covers the screen, seemingly shouting, “Cannot connect!” The entire pop-up message you see may look something like the image above.

The “ERR_PROXY_CONNECTION_FAILED” Google Chrome error is an issue that many users face. While some just opt to walk away, there are others who want to find a way to troubleshoot it. Let’s learn the meaning of this error and how to fix it once and for all.

What Does the err_proxy_connection_failed Error Mean? 

The err_proxy_connection_failed error indicates that there is something wrong with the proxy server or that the IP address is incorrect. Your browser wouldn’t connect to the internet as the proxy connection won’t allow it.

Sadly, this error code means you can’t browse with Chrome until the problem gets fixed. Among the most common causes are the proxy connection being invalid, or a third party controlling the proxy configuration.

Let’s talk about why there is a proxy server and how to fix the issue so you can connect to the internet and go about your day as planned.

What is a Proxy Server?

A proxy server is an intermediary server that separates networks or services and acts like a gateway between the person trying to use the World Wide Web. The internet traffic first goes through a proxy server before connecting to the internet and then forwards the website data back to you. Reasons to use a proxy server include:

  • Security concerns on an open Wi-Fi network
  • Sometimes people in a foreign land use a proxy server to access content not allowed in their country.
  • Companies use a proxy to help prevent data breaches from hackers breaking through their firewalls.

Every device connected to the internet needs to have a unique IP address. Think of it like your home address where other people can find you. Proxy servers connect the Private Internet Protocol IP address and another server on the internet.

Proxy servers have a public IP address on the internet that your computer or mobile device recognizes. They help:

  • Promote web traffic anonymity
  • Control or monitor internet usage by blocking undesirable content
  • Balance web traffic to prevent overwhelming the servers by storing data on multiple servers
  • Create faster network speeds

Why You Might See the err_proxy_connection_failed Error

When you try to connect to a web page, but something goes wrong with the communication between the proxy server and an IP address, you will see an error. 

Besides the “Aw, Snap!” message that means your browser crashed or something went wrong in the Chrome browser, a code appears beginning with “ERR”. This indicates an error occurred and the following words give more insight into what kind of error. 

Other examples of Google Chrome errors are ERR_CONNECTION_RESET, which happens when there’s a misconfiguration in your internet settings, and ERR_CONNECTION_TIMED_OUT, which commonly occurs when the website you are accessing takes too long to respond to the request. We actually have several articles that address various Google Chrome errors, besides those we mentioned.

8. Reset TCP/IP

TCP stands for Transmission Control Protocol, a communications standard that enables application programs and devices to exchange messages over a network.

The Internet Protocol (IP) sends data from one device to another across the internet between computers and networks. Every device has its specific IP address.

The communication works through the Internet Protocol Suite, TCP/IP, a group of communications protocols, split into four layers. Sometimes, the TCP/IP needs to reset for devices to connect through the Proxy to the internet.

Reset the TCP/IP by following these steps:

  1. Press the Windows Key + R to open the Run box
  2. Type: cmd
  3. Press Control + Shift + Enter to open the Command Prompt as an administrator
  4. Type: netsh winsock reset – Hit Enter
  5. Type: netsh int tcp reset – Hit Enter
  6. Type: netsh int IP reset – Hit Enter
  7. Type: Exit – Hit Enter to close the Command Prompt
  8. Reboot Windows

If you still see an error when connecting to a web page, try the next and final option to solve this issue.

9. Renew IP Address

A computer on the internet can have either a static or a dynamic IP. Most use a dynamic IP assigned to a network as needed and changes over time. A static IP address stays the same.

If you use a static IP address, you must set it again once you turn on the computer. It is also possible that issues with the IP address can cause the error message. Releasing and renewing the IP address could help. Do so by following these steps: 

  1. Right-Click on the Windows Key to open the Command Prompt
  2. Select Command Prompt/Admin
  3. Type: ipconfig /release then hit Enter
  4. Type: ipconfig /flushdns then hit Enter
  5. Type: ipconfig /renew then hit Enter
  6. Type: Exit then hit Enter to close the Command Prompt
  7. Restart your computer
