This sounds like a DNS issue or index configuration issue. Are you using a custom index URL which doesn't exist (or doesn't resolve in your environment, perhaps you're using a corporate-only index URL)? Try to curl https://pypi.org and see whether your system can even resolve and connect to PyPI.

You will probably be better served by reaching out to peers or help forums, such as Python Discuss help category, /r/learnpython on reddit, Python Discord's #python-help channel, #python on Libera.chat (IRC), python-list or python-tutor mailing lists, or StackOverflow.

Closing due to the lack of any follow-up which keeps this issue unactionable.
