Python pip3 : Getting ConnectionResetError: [Errno 104] Connection reset by peer when installing python-dateutil

Question

I am trying to install botocore and boto3 package but I am getting following error

[]$ pip3 install --user botocore

It is failing at installing python-dateutil. If I try to install this package itself separately, then also same issue. I also tried following

pip3 install -i https://pypi.python.org/simple/ botocore

and

pip3 install --default-timeout=1000 botocore

But still it is failing with same issue. Python version I am using is 3.7.10. I am not able to figure out the possible reason behind this failure.
