Confirm with your service provider (if accessing from home) or your company IT department (if accessing from a workplace) that they allow access to proxy servers (this is what the off-campus access service uses).

Confirm also that they allow access to ports:

80, 443, 1701, 1601, and 8991

Access to these ports is required by the off-campus service.

Use of a firewall (either a personal one at home, or a firewall in place in your the workplace) may also affect access. The firewall needs to be configured to allow access to the ports above, to accept the proxied IP address which will be returned when you connect to Off Campus Access, and to accept certificates and cookies.

For some firewall software the easiest solution is to put in an entry for to be a trusted site so firewall rules don't affect access.

Also, ensure that you are not using a bookmark to access the library website or to a specific resource (e.g., database). Pages in databases often change URLs. Delete the bookmark and start afresh by going directly to the library website every time.

If you are still having difficulty, please contact the Library.
