# What should candidates do if the test link is not opening?

If the test link is not opening, the candidate should follow these steps in order:

1. Do a hard refresh of the page (Ctrl + Shift + R) once.
2. Copy the test link and try opening it in an Incognito or Private window of a different browser.
3. Switch their internet connection — if they're on Wi-Fi, switch to a mobile hotspot, or vice versa — and refresh the page.
4. Check that their camera, microphone, and browser are all up to date.
5. If none of the above work, try a different device.

||| The candidates must not close the test tab under any circumstances, as this may affect their test progress.
