FTP - Too Many Connections

[LexLuthor]

Asus RT-AX86U with current Merlin firmware. I use foldersync to schedule photo uploads via ftp daily. Last week and then again last night, the upload has failed due to too many connected users. At that point, I tried to connect via WinSCP and confirm the error. Last time, I just updated the maximum number of conncted users in FTP share and that fixed it. But how can I tell what these connections are? Are they phantom connections where maybe sometimes foldersync isn't closing down or could I have other people that I don't know about connected to me via ftp?

More context may help. What router, what firmware? Are you having an issue FTP'ing to a USB device connected to the router from within the local network? Or are you FTP'ing from a remote location to your router and to a USB device connected to the router? Or are you trying to FTP to some other device on your local network from either within or outside your local network?

PS: I don't use FTP to access a USB device connected to the router, but you may want to review the router system log to see what, if anything, it may show for FTP connections. Keep in mind FTP is not a secure protocol. It is best to use other more secure methods of file transfer including VPN or SFTP for remote access.

Asus RT-AX86U with current Merlin firmware. I'm on the local network and the FTP connection is to a USB Hard Drive directly connected to the router. I didn't see anything about FTP in the system log.
One note is that I do have TLS disabled. I can't get foldersync to connect with that enabled. Enable WAN access is on, allow anonymous login is off and number of connections is set to 3. I don't think I need WAN access so I could probably be safe that way, but I'd prefer knowing if there are/were external connections before I make any changes. I would have thought there would be a way to see what's currently connected via FTP, but I don't see a way.
