Guide overview
This guide explains how to resolve the issue of an ‘authentication expired’ error message (see image below). The error prevents users from logging into HYMS Blackboard. This issue persists even when the user clicks on return to login page and attempts to sign in again. Users can follow the two steps detailed below – Step 1: clear your browser’s cache and cookies, and then Step 2: upon log out always choose to end the SSO session.
Please also see our general HYMS Blackboard log in help page, which details all log in steps you will need to know after resolving this issue: how to access the new Hull York Medical School Blackboard Learn Ultra.
Step 1: clear your browser’s cache and cookies
Please clear your browser’s cache and cookies. Please see the below example steps of how to do this in common browsers.
Clearing your browser’s cache and cookies removes temporary copies of a website and it’s files on your device. You can then access sites with a ‘clean slate’. Please note that account passwords, website preferences, and settings may also be cleared. You may also be logged out of work currently open. Please see our other guidance page to alternatively access content in a private browser if you do not wish to clear cache: how to access the new Hull York Medical School Blackboard Learn Ultra.
Google Chrome
- Go to you browser settings and search to clear browsing data.
- Check the boxes for browsing history, cookies and other site data, cached images and files. Click on clear data.
- Completely close all tabs / windows and restart the browser.
Firefox
- Go to you browser settings and search for the cookies and site data section. Please click on clear data. Then click clear.
- Completely close all tabs / windows and restart the browser.
Safari
- Go to preferences, then select privacy.
- Click on manage website data. Click on remove all.
- Completely close all tabs / windows and restart the browser.
Microsoft Edge
- Click on the settings and more icon (ellipsis symbol). Click on settings.
- Under clear browsing data, select choose what to clear.
- Select browsing history, cookies and saved website data, cached data and files, and tabs I’ve set aside, and then select clear.
Step 2: upon log out always choose to end the SSO session
To prevent this error from occurring in the future, always select upon sign out to end SSO session.
This will log you out of Blackboard and also Office365 if open in the same browser (even if you have previously set up to stay signed into Office365 as a preference). Be mindful that this option will therefore log you out of Office365 work if open in the same browser.
When you sign out you will be presented with the option to end the Blackboard session and log out or continue SSO session. *If you do not select an option, you will automatically be logged out after two minutes.
- Choose to end session and log out. You will then be prompted to confirm and end session.
- You will then see a confirmation message.
