Question:

unable to solve error: Timeout while receiving data to output on sFTP

Nov 14 '14 at 11:54

I have an application that checks for files on a secure ftp server every 30 minutes. At least once or twice a week, I receive a "Timeout while receiving data to output" message when downloading a file. I have had the administrator of the server look at his logs and they show a successful transmissions. Is there anything that anyone recommends that I check or change?

Answer

Erik,

I can't think of anything. The LastErrorText indicates that the data connection was established. At that point, Chilkat is waiting for data to arrive on the data connection, but it never arrives..
