The ERR_CONNECTION_REFUSED error frequently occurs when a web browser, like Google Chrome, is unable to connect with a website’s server. This error indicates a disruption in the communication between the browser and the website, hindering access to the webpage.

Contrary to what the term “refused” suggests, this error is typically caused by client-side issues or network problems, rather than the website actively denying access.

There are several potential causes for the ERR_CONNECTION_REFUSED error, each with different levels of difficulty and ways to fix them. These include:

  • Unreliable internet connection. A weak or unstable internet connection can prevent the browser from reaching the website’s server.
  • Chrome extension conflicts. Certain browser extensions may interfere with the website’s loading process, leading to connection issues.
  • Antivirus or firewall interference. Advanced security software might mistakenly block the browser’s access to certain websites.
  • Incorrect internet settings. Misconfigured network settings on the user’s device can lead to connection problems.
  • Browser cache and cookies. Corrupted cache or outdated cookies might cause issues when loading websites.
  • Server downtime. The server of the website you are trying to access might be down or experiencing issues.
  • VPN or proxy interferences. Using a VPN or proxy server might lead to connection conflicts or restrictions.

Each of these causes requires a specific approach for troubleshooting and resolution. Identifying the root cause is the first step in resolving the ERR_CONNECTION_REFUSED error.
