Web Login Service - Stale Request

Display

Description

The GlobalProtect Remote Access VPN utilizes Penn State's WebAccess system for authentication.  The authentication workflow loads the WebAccess authentication page into a browser kiosk-mode window. The connection to the WebAccess login page is initiated from the computer's network interfaces.  This traffic is not redirected through, tunneled through, or initiated from the GlobalProtect VPN systems.  So, issues connecting to WebAccess are in the path between the originating computer and the WebAccess system located in Penn State's University Park or Hershey Data Centers.

Resolution

• Verify that there are no local browser or system issues on the originating computer
• Ensure the ability to load https://webaccess.psu.edu in a web-browser, and authenticate with PSU credentials including DUO 2FA.
• Ensure the ability to load https://login.microsoftonline.com in a web-browser. Enter PSU username in format of userid@psu.edu (ex. abc123@psu.edu) and ensure that the page redirects to webaccess.psu.edu
• Verify no local LAN, WiFi, or ISP connectivity issues are present on the originating computer side of the connection. (ping, MTR, Win-MTR, etc. to various Internet destinations)
• Verify a reliable and error-free Internet path is available from the originating computer to Penn State's network.(ping, MTR, Win-MTR, etc. to secure-connect.psu.edu)  

Script Error - An error has occurred in the script on this page.

Display

Description

Resolution

Clear the cache in the Internet Explorer browser

  • Unselect Preserve Favorites website data 
  • Select Temporary Internet files and websites files
