On Windows 10 this can appear if Windows' local cert store doesn't have a good cert for pypi.org. I have successfully solved this for myself by loading pypi.org in Edge, thereby updating Windows' cert store.

(( Must be a browser that uses Windows' own cert store. To my knowledge Firefox doesn't (for good reason) ))
