Assuming there is no known temporary problem with the resource you are trying to access (for service interruption notices see Library Blog) this is likey to be caused by something in your local PC/Browser setup. These often fall into one of the following categories:

 

Firewall

 

Firewall problems often present themselves as hanging web pages which often eventually result in a connectivity error from your browser. If you are behind an organisational firewall try testing access to the same resource from a PC outside of any organisational firewall, and if necessary temporarily disable any PC local firewall via your own PC's firewall configurations. (Note that most personal home PCs/laptops do not by default have local firewalls configured).

Institutional firewalls may block port 50080. This would cause failure in connecting to QUB e-Resource with URLS of the following form:

http://encore.qub.ac.uk:50080/jstor/

If your browser is hanging trying to access the above link you need to have port 50080 opened on your institution/local firewall.

 

Browser popups

 

Browsers can have various settings which affect access to e-Resource pages. Pop-up blockers are one of the more common causes of access problems. You may typically see inactivity after clicking a button/link which should normally open a new window. Sometimes you may notice a security notification message in your browser’s information bar when this happens. To avoid pop-up errors add *.qub.ac.uk as a trusted site in your browser's pop-up settings.

 

Browser PDF handling

 

Each browser has its own settings to control how PDFs open from a web page. If you are having problems opening PDFs the following adobe page will help you configure your browser:

Note:  A good way to confirm whether or not your problem is caused by your local PC setup would be to test access from a different browser and/or PC outside of any firewalls.
