Answer 1

If you call the IP address 127.0.0.1/localhost then you are communicating with the localhost – in principle, with your own computer.This issue also appears when you don't have localhost configured

For Linux systems

• Add/Edit "127.0.0.1 localhost" under /etc/hosts if its missing.

For Windows system

• Add/Edit under C:windows/system32/drivers/etc/hosts if its missing.

For more details on localhost
