Fix Chrome Authentication Error (Version 142 and Later)

If you are using Chrome version 142 or later, you may encounter authentication errors when accessing college systems. This is caused by a new Chrome feature called "Local Network Access Checks" that is enabled by default.

What the Error Looks Like

You will see this message: Authentication Failed - Problem in external authentication service

Solution 1: Disable Local Network Access Checks (Recommended)

Follow these steps to fix the issue:

1. Open Chrome browser
2. Copy and paste this into your address bar: chrome://flags/#local-network-access-check
3. Press Enter
4. Find the "Local Network Access Checks" setting
5. Change the setting from "Default" or "Enabled" to Disabled
6. Click "Relaunch" to restart Chrome
7. Try accessing the portal again

This should resolve the authentication error immediately.

Solution 2: Downgrade Chrome Version

If Solution 1 does not work:

1. Uninstall Chrome version 142
2. Download and install Chrome version 141
3. Disable automatic Chrome updates temporarily

Solution 3: Use an Alternative Browser

You can also use one of these browsers instead:

• Mozilla Firefox
• Microsoft Edge

Both browsers work without any configuration changes.
