FTP Connection Error

As broached in an unrelated thread, I am receiving errors every minute: "Error reconnecting ftp server".
After turning on FTP Logging as well as adding Logging=1 and DataLogging=1 to the cumulus.ini file, the new logs are attached.

I'd like you to update to the latest version of MX please.
Also I need to see the FTP log file.
Which FTP protocol are you using? The error indicates a problem at the server end though - it is closing the connection before it has finished establishing it.

Good morning. Just updated to 3086. Both logs attached. Also, it's set to use just regular FTP.

I see it is trying to connect to an IPv6 address for your FTP server - is that expected?
You also have FTP Active mode enabled, any reason for that?
It could be a firewall on your computer or router blocking the FTP connection - you could try disabling Active mode as a test to see if that improves things.

Hm, no idea why. IPv6 isn't even enabled in my environment.

I don't have a specific reason that I can recall as to why it is on. I'll turn it off and see if it helps. The local firewall on this server isn't blocking it, but maybe it's something related to my pfSense firewall. I'll look into it. Again, I don't have any need/reason to FTP data out of my network, but I still want to get rid of this error if possible.

So, I disabled Active FTP and that made no difference. I turned on IPv6 on my firewall and setup DHCPv6 for my server. That also made no change. I then changed my IIS FTP binding from my servers local IPv4 address to a wildcard, and now I keep getting the below:

I'm starting to wonder if I should employ the "if it's not broke, don't fix it" strategy here

OK, so yes MS will use IPv6 addresses on your local network by default, but your IIS wasn't bound to the IPv6 address.
Now, the error is saying IIS does not support file rename overwrites - so you will have to disable the "FTP Rename" option. If that still fails, then try that in combination with "Delete before upload". Or switch to using a decent FTP server

Yes, looks like disabling FTP Rename did it. Thanks for the help.
