HTTP 500 Internet Server Error

With updates that have been made to browsers such as Chrome, Safari and protection changes made by ZScaler some users have been receiving an error like the following;

"HTTP 500 Internet Server Error"

To fix this problem you need to delete your cache.

CHROME

In Chrome, you do this by clicking on the menu and select “Clear Browsing Data…"

Then in the Time range change it to “All time”

Deselect the “Browsing history”

Click on "Clear data" and try accessing the internet again.

SAFARI

Cleaning cookies and the cache data for individual sites can be done by opening the Preferences dialog box, then selecting the Privacy icon and clicking the "Manage Website Data..." button.

You can then prune the list manually by selecting an individual site and clicking the Remove button, or delete all cookies and cache by clicking the Remove All button. There's a search field you can use to track down individual sites.

Bear in mind that deleting cookies might remove autocompleted login usernames and passwords for sites, and will almost certainly log you out of that site if you've configured it to automatically login each time you visit.

Once you have cleared the data, try accessing the internet again.
