Why are my off campus patrons receiving an error message that says "Null Relay: HTTP session was not found" when they try to access the user portal?

Applies to
  • Tipasa
  • EZproxy
Answer

If off-campus patrons are receiving this error message, you may need to update your EZproxy config.txt file to add NeverProxy lines for Tipasa. If you use Hosted EZproxy, please contact OCLC Support to have this added.

If you use EZproxy Software, you will need to add the following lines to your config.txt file and restart the EZproxy service:

For the Dublin data center:

NeverProxy https://authn.sd00.worldcat.org
NeverProxy https://[registry_id].account.worldcat.org
NeverProxy https://[my institution].account.worldcat.org 

For the Amsterdam data center:

NeverProxy https://authn.sd02.worldcat.org
NeverProxy https://[registry_id].account.worldcat.org
NeverProxy https://[my institution].account.worldcat.org 

For the Sydney data center:

NeverProxy https://authn.sd03.worldcat.org
NeverProxy https://[registry_id].account.worldcat.org
NeverProxy https://[my institution].account.worldcat.org 

For the Toronto data center:

NeverProxy https://authn.sd04.worldcat.org
NeverProxy https://[registry_id].account.worldcat.org
NeverProxy https://[my institution].account.worldcat.org 

Replace [registry_id] with your library's OCLC Registry ID (i.e. https://1234.account.worldcat.org)

Replace [my institution] with your library's custom WorldCat prefix (i.e. https://mylibrary.account.worldcat.org)
