Can't login to Battlenet - no fixes work

Hi,
Before I even enter my password into the Battlenet opening screen, it tells me I can’t log in. I am on a mac mini with an ethernet connection - which works fine in all other apps. I have tried rebooting the modem, I have tried deleting the battlenet folder, I have restarted the computer etc. Internet is working fine, but Battlenet won’t connect. I have tried shifting regions, using VPN etc.
What do I do?

Wrong forum. The Mac forum is here: Desktop App Mac Tech Support

In the meantime, try a new DNS or a different VPN.
