You need to connect to your VPN client first and then access the full text.
If you ever failed to follow this order, you would have to
- restart your browser (alternative: you can also delete the cookies set by the publisher)
- connect to the VPN client
- and then call up the full text.
Background: when accessing the full text, most publishers set cookies to record access permissions. Shutting down the browser deletes them and then creates them again, this time taking the VPN connection into view.
How do I recognize an internal VPN client?
You can find out by right-clicking on the Invanti Secure icon in the SysTray (lower edge of the screen) and selecting "Open Ivanti Secure". The "Server URL" should then be "vpn.tu-dortmund.de", without any other additions.
Background: with an internal VPN client you can only access resources on servers of the TU Dortmund - but our e-books are usually located on the servers of the publishers or at other providers. (List: 'Internal profiles' of the deparments at the TU Dortmund)
Please try the call with another browser or e.g. with the private mode of Firefox. Or temporarily disable your browser plug-ins.
For the 'Ad Guardian Plus' you can also deactivate the HTTPS traffic (s. Manual).
Also possible: the ebook has accidentally not been unlocked for use or the ebook you are looking for has mistakenly been added to the list of licensed titles - please send us an email and tell us the title you are looking for. We will contact the publisher.
For many publishers we now also offer authentication via Shibboleth ('institutional login').
Since March 23, 2023 there is a new version of the VPN client Ivant Secure (version 22.3R1) - download.
Note: you can determine the version of your VPN client by opening the Ivanti Secure window via the corresponding icon at the bottom of the screen. Via "Open Ivanti Secure" you can find the version number of your VPN client under 'Help' and 'About'.
Please note our blog post Elsevier-Zeitschriften ab 1.1.2017.
You would have to switch off the other VPN client while using Ivanti Secure - this can also cause interference.
Please connect via Ivanti Secure and then go to https://ct.de/ip in your browser. The page will show you the IP address you are currently using - the address should start with 129.217.
The Ivanti Secure icon in the SysTray (bottom of the screen) should have a colourful background when the connection is active.
If you have problems with the performance of your VPN, please restart your home router.
