Problems Connecting to AMICUS

The National Library cannot troubleshoot specific Z39.50 client software problems. Use the guidelines below to diagnose the problem and then contact your Z39.50 software vendor for support.

  • Host Not Found: Your Z39.50 client is unable to locate the AMICUS Z39.50 server. Check the "Server Address" / "Domain Name" (see above). If correct confirm that your "Domain Name Server" is working correctly. Check if your network uses a firewall; it may be preventing Z39.50 traffic.
  • Connection Refused: Your Z39.50 client was able to locate the AMICUS Z39.50 server but did not allow a connection. The AMICUS database could be down for maintenance. Check that your AMICUS username and password are still valid. Some Z39.50 clients do not display errors being returned.
