There are two reasons why this can happen.
- If you are using a laptop on WiFi and recently changed your password
- If you are using Internet Explorer or a mapped drive
For the first issue, the password sync between your laptop and WiFi has not occurred yet. You need to log into your laptop and make sure the new password has synced with your computer via WiFi. Try logging back out and in to make sure your new password is working. Then try to access the documents again. If this doesn't work, you will need to plug in an Ethernet cable to your laptop or docking station to get online via a wired connection rather than wireless.
If you are using Internet Explorer or a mapped drive, you will need to update a setting in Internet Explorer to correct the issue. Follow the path below to find the setting and add the SharePoint base URL to the trusted local intranet zone.
Internet Explorer > Internet Options > Security Tab > Zone: Local intranet > Sites button > Advanced button > Add: https://sp.valenciacollege.edu to the zone and save this setting. Click OK to close the dialogs and try to open the documents again.
