I went to log in after patching, and everything seemed fine, until  the point where I get to the connect splash screen.  I press the "start" button to open char select screen , and the Game ends with "Failed to Connect" dialog  box and closes.

WTH???  It's been working fine and nothing on my end changed.   How to fix?

UPDATE:  They changed some firewall and port settings with the local client last patch that violated my firewall rules.  On my local PC I had to explicitly let blackdesert.exe past firewall checking.  This fixed the issue for me.
