Download error on https://pypi.python.org/simple/pms5003/: [Errno 107] Transport endpoint is not connected – Some packages may not be found!
Couldn’t find index page for ‘pms5003’ (maybe misspelled?)

can anyone help please

Probelm solved now the URL is now active.

script worked ok.

enviro+ working fine.
