pip install not working -- (ERROR: Could not find a version that satisfies the requirement Flask (from versions: none))

I am trying to download modules to python using pip and it is not working.

python vesion - 3.9.2

pip version - 20.2.3

windows 10 (updated to the most recent patch)

The error(the same error happened with Flask, scapy and ipython):

the computer is trying unsuccessfully to reach the package 4 times:

WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ReadTimeoutError("HTTPSConnectionPool(host='pypi.org', port=443): Read timed out. (read timeout=15)")': /simple/scapy/

then this error pops:

ERROR: Could not find a version that satisfies the requirement scapy (from versions: none)

ERROR: No matching distribution found for scapy

I have tried using pip3, downloading through pycharm, updating python from 3.7.9 to 3.9.2 and I have checked that the path is added to the enviroment variable (Path=C:\Program Files\Python39\Scripts\;C:\Program Files\Python39\;{....})

What else can I try? Thanks in advance!
