After loading Niagara G3 3.6 security updates released on August 9, 2012, a web browser session times out after 5-10 minutes, requiring the user to login again.

Issue

After loading Niagara G3 3.6 security updates released on August 9, 2012,  a web browser session times out after 5-10 minutes, requiring the user to login again.

Environment

Niagara G3 station web enabled

Web browser; Internet Explorer, Firefox, Chrome, etc.

Cause

From the Release Notes for the Niagara 3.6 Security Patch, "Changes to File Access":

"The default Authentication Scheme for web access has changed from "Cookie" to "Cookie Digest", as specified in a station's Web Service. As a result, custom login templates may need to be modified to work properly."

Note: The complete Release notes are contained in the securityPatches_3.6_083112.zip file on The Exchange Download Center website, Tech Zone, I/A Series G3 (ENC, ENS, etc) Conference, Release 3.6.47 Files.

Resolution

  1. Increase the Cookie Digest Session Timeout.

    If you increase this timeout, but still notice that it is taking you back to the login screen well before the time should have run out on the session, then it is a different issue.
  2. In that case, upgrade your JAVA plugin to the newest possible version and install the Security Patch (both of which are recommended regardless).
  3. Be certain that it is not an issue with firewall, antivirus, internet security, etc.
