An error message “Timeout detected” while attempting to access FTP with WINSCP

Possible scenarios

1) Network error: Time out during connection

All sort of connection refused by other end apply to this Error too

2) Timeout Detected

This error occurs while log in and attempting for a file transfer

3) Problem with host communication for more than 15 seconds

You can see this message while WNSCP is waiting for response from the server more than the configured time. This is not an error message but WINSCP keeps waiting for the server to respond. The message is shown to give you a chance either to break the operation and try again to reconnect. This option is given if you do not want to wait anymore. If the server connects then the message will be delivered automatically. If the host server did not respond back, then it may be due to some fatal error on the server side. Also, sometime this may be interfering with the connection and preventing the server response from arriving on the configured time

4) Permission not granted

If you don’t have sufficient permission to a resource such as file or directory, you should contact the server administrators to solve the issues. Access right to a system differs between OS and file transfer system

If the stream is not read from then eventually the buffer get filled and winscp gets hanged. If that is trying to write into it most commonly the program is run by another program, which redirects to the output stream.
