PIO Plus login error

I can’t log in to PIO Plus
I am connected to the internet.
I’ve rebooted the mac and still thinks I’m not connected.
Any suggestions please.

If you build a project first time, we need Internet connection to install all dependencies and toolchains.

Do you use proxy? Do you have firewall? Littlesnitch, etc?

Little Snich was the problem thanks.
PS Don’t know suddenly it decided to block platform io though
