Connection timeout
There are a few different reasons that a connection timeout can occur:
Slow or unreliable connection
Somewhere between your local machine and the host server is a slow or unreliable connection.
To counter this:
- In the main menu, click on Edit > Settings….
- From the menu on the left, select Connection.
- Increase the number in the Timeout in seconds field.
- Click on OK.
Incorrectly configured server
If the connection times out on large file transfers, a server somewhere between your local computer and the remote server might be incorrectly configured, identifying the command channel of the connection as ‘idle’, and closing it. This is a misconfiguration, and ideally should be handled by opening a support ticket with the owner of the server.
You might be able to counter it temporarily:
- In the main menu, click on Edit > Settings….
- From the menu on the left, select Connection > FTP.
- Tick the Send FTP keep-alive commands checkbox.
- Click on OK.
