My connections to the server seem to time out rather quickly. I get the following messageStatus: Disconnected from serverResponse: 421 Connection timed out.Error: https://kb.globalscape.com/KnowledgebaseArticle10142.aspx Disconnected from server: ECONNABORTED - Connection abortedSeems to happen after about 1-2min. Is there a timeout setting that I should modify? Or is this indictive of a larger problem. Everything else seems to work fine.

Is there any reason it is set for such a short timeout? Is there a reason I shouldn't set it for say 30min?Cheers for the help.

I've set it to 6 hours on my server. Filezilla Server only allows 9999secs max, though. _________________### BEGIN SIGNATURE BLOCK ###No support requests per PM!

good, bad or incomplete: Range Purpose 1xx Positive Preliminary reply The requested action is being initiated; expect another reply before proceeding with a new https://en.wikipedia.org/wiki/List_of_FTP_server_return_codes command. (The user-process sending another command before the completion reply would be http://stackoverflow.com/questions/24799518/ftp-response-421-received-server-closed-connection in violation of protocol; but server-FTP processes should queue any commands that arrive while a preceding command is in progress.) This type of reply can be used to indicate that the command was accepted and the user-process may now pay attention to the data connections, for implementations where ftp error simultaneous monitoring is difficult. The server-FTP process may send at most, one 1xx reply per command. 2xx Positive Completion reply The requested action has been successfully completed. A new request may be initiated. 3xx Positive Intermediate reply The command has been accepted, but the requested action is being held in abeyance, pending receipt of further information. The user should send another ftp error 421 command specifying this information. This reply is used in command sequence groups. 4xx Transient Negative Completion reply The command was not accepted and the requested action did not take place, but the error condition is temporary and the action may be requested again. The user should return to the beginning of the command sequence, if any. It is difficult to assign a meaning to "transient", particularly when two distinct sites (Server- and User-processes) have to agree on the interpretation. Each reply in the 4xx category might have a slightly different time value, but the intent is that the user-process is encouraged to try again. A rule of thumb in determining if a reply fits into the 4xx or the 5xx (Permanent Negative) category is that replies are 4xx if the commands can be repeated without any change in command form or in properties of the User or Server (e.g., the command is spelled the same with the same arguments used; the user does not change his file access or user name; the server does not put up a new implementation.) 5
