Select "Options" from Zotero connector listed in your browser's extensions.
Under the "Proxies" option in the Proxy Settings section, uncheck the "Enable proxy redirection" box.
The "Enable proxy redirection" setting automatically adds proxy redirection to links. However, we already add a proxy to links to OHSU Library databases and journals. Adding a proxy in this section creates a "double proxied" link, which can cause issues.
For best results finding full-text PDFs, please make sure to sign in via the Library's OpenAthens authentication system or another OHSU application using Single Sign On (SSO, aka Shibboleth).
