Could someone explain to me how can I configure the Httrack 
to fix the following errors found in the log:

Error:  "Connection refused: *read error" (-1) at link ...

Error:  "Time out (300)" (-1) at link ...

Error:  "Bad user name: *read timeout (300)" (-1) at 
link ...

Error:  "RETR command errror: Failed to open file." (-1) at 
link

Thanks,
Jesse
