The first thing you should do is perform some basic troubleshooting on your own PC and internet connection.

To troubleshoot, you should do the following:

● Try going to other websites and compare the performance of those sites to the CAS


● Clear your browser's cookies and cache, check to see if the slowness/unresponsiveness is still occurring after

● Use a different web browser (Microsoft Edge, Firefox, Brave, Chrome)

● Reboot your PC

If you have done all of the above, but there is still an issue with the CAS portal, go ahead and visit our Itopia Status Page at to check if we are having issues with our portal.

Now, if the Itopia Status Page shows that the main portal is operational, and the CAS portal is the only website that's running slow for you, the next step would be to generate a HAR file and email it to with a description of what exactly is going on. You can find out how to generate a HAR file below.

How To Generate A HAR File

HAR file is used for tracking information between a web browser and a website. A HAR file is primarily used for identifying performance issues, such as bottlenecks and slow load times, and page rendering problems. The HAR file keeps track of each resource loaded by the browser along with timing information for each resource.

The steps provided below are for Google Chrome, however, a HAR file can be generated on different browsers. If you’re using a different browser, Click here for a guide on how to generate a HAR file for a variety of browsers.
