Other Common Problems

Proxy (off campus authentication) error

Most proxy issues occur when trying to access an open access title. If you see this message, try accessing the item directly through the publisher link. Also, please let us know about the issue by submitting the report, with email address included.

Connecting to an e-resource

Some resources will not display or function properly depending on the web browser settings. Known common problems are:

  • Using Internet Explorer (IE) and Safari. Chrome and Firefox are your best options.
  • Trying to access an open source article. Our linking service automatically includes the proxy, or authentication, within a journal. This can cause issues when access articles that are free to all. If you see this page, enter your email address and report the problem. Also, try clicking on the link for direct access to publisher.

Off-campus Issues:

  • EZproxy error message - This occurs when trying to access materials from off campus. The proxy service will not work with IE. Log in using your UT Health username/password. The proxy message will also occur when trying to access free articles.
  • Our off-campus login (Shibboleth) does not work well with IE or Safari. If you cannot use Chrome or Firefox, try logging in through the university VPN.

Citation trouble

Citation information is provided by each publisher and does not always link properly (when using HSCLink). Some common problems occur if:

  • Journal does not offer article level linking. This means that the link will probably take you to the journal homepage, and then you will need to work your way down to desired volume/issue.
  • HSCLink is trying to access a supplement. If there is any variation on the standard page number, the linking will not work properly. Click on Browse Journal and work your way down to desired volume/issue.
