Maybe your server is just denied access to external targets on exotic ports. That's the most common cause for that. 2015-12-23 17:34 GMT-03:00 Boulier, Jack <jboulier@mticollege.edu>:

Can anyone explain to me why I am getting connection errors for the Z39.50/SRU option when attempting to catalog new materials? My connection options are Columbia University, Smithsonian Institution Libraries and the Library of Congress. All three give me a connection failed error. The system is connected to the internet, I am able to connect to the system using http. And the server will connect to loc.gov.

Thanks for your assistance.
