Symptom
You are having an issue connecting to a resource through EZproxy, either from on-campus or off-campus
If the issue is from off-campus, confirm the vendor has the External IP address of your EZproxy server correctly configured to access your subscription
If the issue is from on-campus, verify you are proxying their site. If you have ExcludeIP configured in EZproxy for your campus IP range, attempts to access the site will go directly to the site, not via EZproxy. Contact the database vendor and provide them with your Campus IP range. Be sure they also have your EZproxy server IP as well or you will lose off-campus access.
If you still cannot access the database, please contact OCLC Support
