Common issue, not related to Airflow itself.

It is either a problem with connection on your side or something wrong (rare case) with PyPI repository or something bad with Github (happen time to times)

• Check internet connection
• Check VPN connection
• If you use a proxy, then... check it
• In addition you could increase timeouts, see PIP docs https://pip.pypa.io/en/stable/topics/configuration/
