There are a few reasons that cannot access some kind of database, e-book, or full-text journal when the VPN connect successfully and IP address starts with 140.112.
- The VPN server is under maintenance.
- The database server is under maintenance.
- Maximum of users access the database at the same time. For example, "Digitimes" is limited 5 people using database at the same time.
- E-journal may have the embargo situation for the delay to provide full-text access.
- The database would request the user to enter the login account, such as "TEJ".
- The database does not support VPN off-campus connections. You must access the resources within a specific network area or even use specific computers. For example, users are only allowed to access "Statista" in the Koo Library, the College of Social Sciences.
- Adjust the operation order to “Log in to VPN → Enter the database” instead of “Enter the database first → Log in to VPN → Refresh the database”. The database server may save the original IP address previously, and it may cause the VPN fails.
- The database (such as IEEE Xplore) only supports VPN connection via Pulse Secure client, rather than NTU SSL VPN website (https://sslvpn2.ntu.edu.tw). Therefore, you must install Pulse Secure client to connect VPN. Click here to check the installation guide.
If you have those situations, please contact the library for help by phone 02-3366-2326 or email tul@ntu.edu.tw .
