Why am I unable to access certain websites?

Check your internet connection: Make sure your pc or device is connected to the internet by either Wi-Fi or Ethernet cable.
Test other websites: Open a couple of other websites you usually access to test if the issue is with the website in question or your connection.
Check your browser settings: If you are able to access other websites, make sure the settings on your browser haven’t changed.
Check your security software and firewalls: If your security software is blocking the website, make sure you have allowed or whitelisted that particular website in the security software or firewall settings.
Clear your browser cache: Clearing your browser cache might fix the issue if the website you are trying to access has been updated, or if the website isn’t responding.
Restart your router and device: Try restarting both your router and device and checking if you are able to access the website again.
Restart your modem: If restarting the router and device does not work, restart your modem and check if you can access the website then.
