This error redirects you to the default browser on your Chromebook. In most cases, the prompt tells you to return to the host page. This is an annoying error, especially if it persists longer.

What is a network captive portal?

A captive portal is a page that pops up once you connect to a WiFi network, especially if you are a new user. Some people also refer to it as the splash page. It is mostly used by businesses that provide free or paid public WiFi networks.

Captive portals are also used to limit bandwidth, authenticate users behind a firewall, deploy personalized marketing, or restrict internet access for guest wireless clients. However, it can sometimes happen on your normal WiFi hotspots and can be frustrating if you don’t know how to fix the error.

  • Use an Ethernet cable to connect the router to your PC.
  • Write the router’s IP address on the browser’s address bar and load it.
  • Log in as an administrator. If you can’t connect here, you need to contact your ISP.
  • Navigate to the Update or Firmware sections and check for any available updates.

  • Open Settings and go to Network.
  • Select the WiFi network you’re connected to

5] Disable VPN and proxy

Some third-party VPN software and proxies can interfere with your internet connection. You can disable your VPN. The process depends on which VPN you are using. You can uninstall it for a moment and then reinstall it later if it’s not the cause of the captive portal warning on your network.

To disable the VPN on your computer, follow the steps below:

  • Go to Settings > Network
  • Choose VPN
  • Click the VPN connection to toggle it off

According to Google, consumer-owned Chromebooks don’t have a proxy. However, if your Chromebook or account is managed by a school or organization, you can try these steps to disable proxy in Google Chrome:

  • Open Google Chrome
  • Click the three dots in the top-right corner
  • Click Settings
  • Scroll down and click Advanced
  • Under System, toggle off Use a proxy server

You can also open your computer’s proxy settings by clicking Open your computer’s proxy settings under System.

Chrome doesn’t have in-app proxy server settings, so you’ll be redirected to your operating system’s native proxy settings.

Pro tip: It is good to note that in some cases you need to go to the login or authentication page to use the internet, especially if it’s public WiFi or the provider is protecting payment or other crucial websites.

We hope something here works out for you.
