📌 Basic Troubleshooting Steps When Seeing “This site can’t be reached”
✅ Basic Checks
Check the Internet connection
Try accessing other websites to see if your internet is working properly.
Switch networks
Change from Wi-Fi to a mobile hotspot, or try another Wi-Fi network.
If other websites load → the issue may be with the original network, such as DNS or firewall.
👉 Recommendation: Contact the Computer Center.
If other websites still do not load → the issue may be account-specific or system-related.
👉 Recommendation: Contact the LEB2 support team for further assistance.
Try a different device
For example, use a mobile phone or another computer to see if the problem is specific to one device.
Clear cache / restart the browser
