Here is the screenshot of my browser when I tried to reach these websites. For some reason, something is blocking the connection.
Other than that:
- Internet connection is stable, my download speed on steam is 10mb/s
- I am using my school's wifi, I am not sure if others can use those networks, but I can use instagram on my phone using school's wifi.
- I am not using vpn
- I do not have antivirus software running. There may be some service in the deep background running but I don't know.
5.DNS Client is running
6.This problem existed for months. So I tried reboot, and reconnected several times.
- Is there anyway I can check the blacklist of my IP address? Maybe I somehow set a list of websites to block. I remembered I have downloaded a hosts file online to block a lot of websites. But it makes my laptop super slow and laggy, so I deleted it long ago. I will display my current hosts file down below, mainly blocking some porn websites tho.
My current connected wifi properties are like this:

My etc folder:
My hosts file:
