Cannot write to server: not open

[emanuelepavese]

I was in the middle of a debug session, everything was fine. After a few modifications on the code I was working on, I launched the debug and got this error: 

Cannot write to server: not open

LPCXpresso 824 max

Windows 10 

I already tried to reinstall the drivers, but nothing happens. 

(The pc recognizes the board correctly)

What I have to do ??

Thank you

emanuelepavese What specific FIREWALL actions did you take to resolve this?
(simply stating "FIREWALL" does little to help others resolve their issue)
