Please try to disable ipv6...

Howto disable ipv6

Please use this official method to disable ipv6 https://help.ubuntu.com/community/WebBrowsingSlowIPv6IPv4

In short, open Applications → Accessories → Terminal and type

sudo sh -c 'echo blacklist ipv6 >> /etc/modprobe.d/blacklist.local'

give your user password when requested, you don't see nothing when you type it, then press enter.

The above command appends a line to the local blacklist configuration. The file will be created if it does not exist.

To restart your computer, type:

sudo reboot

Hope this helps
