I get the following error sometimes when uploading or downloading: *No activity time-out expired. [1181]
A "no activity time-out" is returned when Robo-FTP is expecting some sort of response from the FTP server but does not receive one.
This is not a common error, and it can mean different things under various circumstances. However, it often means something has gone wrong on the FTP server and it is unable to respond the way it should.
A common way to handle this situation is to check for this error message and handle it by telling Robo-FTP to disconnect and reconnect to the server.
You can use the NATO command to configure how long Robo-FTP should wait for a response in these situations.
Here is an example:
NATO 10
:reconnect
FTPLOGOFF
FTPLOGON "MySite"
SENDFILE "testfile"
IFERROR= $ERROR_NO_ACTIVITY_TIMEOUT GOTO reconnect
This example sets the no activity time-out limit, logs off (this will do nothing if you haven't yet logged on), logs on, sends a file, then loops back to try again if the upload fails due to hitting a no activity time-out.
