To fix it, you can create pip config file and add a list of trusted-host to pip config file as below:

PS C:\Users> mkdir ~/pip
PS C:\Users> ni -Type File ~/pip/pip.ini
PS C:\Users> explorer ~/pip/
// copy below string into C:\Users\<username>\pip\pip.ini file, 
// input below content into the newly created file, beware of  invalid characters error
"[global]
trusted-host = pypi.python.org
               pypi.org
               files.pythonhosted.org"
proxy = http://<proxy-server-address>:<port> // additional setting in case your network connection has proxy configuration
