In some cases It's only because of poor or interrupted internet connections

One solution might be changing your internet form Wi-Fi to Ethernet.

If you are using ESET antivirus, go in "Advanced Settings" and disable "HTTP-scanner" under "web access protection"

If you're using Virtualbox, Then you might need to downgrade to resolve the issue

If you are using IPv6, try disabling it. 

sudo sh -c "echo 'precedence ::ffff:0:0/96 100' >> /etc/gai.conf"
