When accessing college resources from off campus an error my be displayed in the users browser during the authentication process

This more commonly appears if using Chrome web browser

The college supports the following web browsers in order of preference:

  • IE both version 11 and Edge
  • IE 10
  • Safari
  • Firefox
  • Chrome and all derivatives  

For some users of the browser, no data received may appear completely random as they may be able to load sites right after the error, or may not experience it at all for a prolonged period of time.

Anyway, when the error is displayed you get two options on the screen. The first allows you to reload the page which works similar to hitting F5 on the keyboard or using the reload button in Chrome's interface.

The more button on the other hand reveals additional information about the error. Common messages that you may get here include Error code: ERR_EMPTY_RESPONSE, ERR_TIMED_OUT, Error 324 and the server closed the connection without sending any data.

You can try a couple of things to load the website correctly:

  • If reload has not worked, try the shortcut Ctrl-F5 which reloads the page bypassing the local cache.
  • Press F12, select Resources in the Developer Tools interface that opens up, and there cookies. Right-click on any domain listed here and select clear to remove cookies from it. Try to reload the page afterwards.
  • Press Ctrl-Shift-n to open a private browsing window and try to open the website or service in that new window.
  • Try to load the website with the correct protocol directly. If you want to open a site available using https://, use this directly when opening it and not http:// (use the links from the portal page rather than any favourites).
  • Try another browser. Download a portable version of Firefox, or run Internet Explorer or any other browser available on your system. This is just to verify if it is a issue of Chrome or a system-wide issue. If you can open the site in the other browser, it is a Chrome-specific issue.
  • You can also try to use a mobile browser to connect to the url if you have one available.
  • Try using a web proxy server to connect to the site. Make sure you don't use it to sign in to a service or use it to make purchase or reveal other sensitive data but only to check if the site or service loads when it is used.
  • Try to disable add-ons and scripts that may be running in the background. Open http://chrome://extensions/ and disable them all, or disallow them to run in incognito mode and run that mode again.
  • Make sure that the site in question is not blocked by security software, firewall or other means such as the hosts file or an ad-blocker. This can be difficult to assess depending on how many programs you have installed and how well you know your way around computers.
  • If you are using a VPN, try to disable it if at all possible.
  • Scan the computer for viruses and other malware using software such as Malwarebytes Anti-Malware. It is free, powerful and can run next to any installed security software you may have.

Restart the computer and router.
