How to resolve connection failure & timed out error messages

Connecting via EZproxy links

Some users have reported seeing error messages when connecting to resources via EZproxy links, both on and off campus.  Usually these links are in iDiscover or in the ejournals A-Z.  Over the next several weeks we are aiming to upgrade our EZproxy server, which we expect to have a beneficial effect regardless, and will be the first step towards resolving the issue.

Typical messages users have reported are: “Connection to was interrupted while the page was loading”, “This site can’t provide a secure connection” or a time out message. As we do not have a solution now, we offer the following work-arounds.  If none of these work for you, please report the issue using the form here.  Thank you for your patience.

These steps should be followed in order to regain access:

  • Clear all the cookies, browsing history and cache of your browser and restart it. It is important to choose the option to delete ‘Everything’ (Firefox), from ‘the beginning of time’ (Chrome), or any equivalent time span in the browser you are using, in order for this to be effective
  • Try using a different browser entirely.
  • Perform a complete browser refresh/reset (for example using Firefox instructions here). This will reset the browser to factory settings and users may not want to do this if they use add-ons on their browser as they may lose stored passwords and data.
  • Locate the resource on a publisher’s site and access it via Shibboleth/institutional login (if you need any assistance with this please contact us using the form here)

  • iDiscover  will search for articles, ejournals, ebooks, databases, and all other electronic material.
  • Journal Search limits your iDiscover search to ejournals only. You can also search via the A-Z of ejournal titles.

ravenIf you are off campus you generally need to log in to Raven to access online material. A Raven log in screen should appear when you click on the link for a journal.

Raven passwords are available to current staff and students of the University of Cambridge. If you have any questions about Raven then please see this page of FAQs from the Central Science Library.
