I can connect to WiFi but all websites refuse to connect I have a device running Android version 5.0.2 that connects to our WiFi network, but browsing to any website using Chrome displays a page with:


  The site can't be reached


and


  ERR_CONNECTION_REFUSED


This device used to connect without a problem

I also have a second device running Android version 4.2.2 that still connects to the same network without any problems.

How can I troubleshoot the first device?
Try using a VPN, I recommend Thunder VPN if you are an Android user.

So far, this is the only solution that I thought of and that is what worked for me, but there are also other VPNs.
