I am getting following errors repeatedly upon using apt-get update command :

pi@raspberrypi:~ $ sudo apt-get update

Err:1 http://raspbian.raspberrypi.org/raspbian stretch InRelease
Cannot initiate the connection to raspbian.raspberrypi.org:80 (2a00:1098:0:80:1000:75:0:3). - connect (101: Network is unreachable) [IP: 2a00:1098:0:80:1000:75:0:3 80]

Also the browser isn't responding .

I tried to connect with a ethernet cable from my laptop and directly from Wi-fi but I got the same results.

My ifconfig -a
