Hey @n8nonmac,

What FTP server are you uploading to?

kentucky.o2switch.net - the one I usually use. I can connect without problems on Filezilla

Hey @n8nonmac,

Can you enable the debug logging in Filezilla and send over the output? I suspect it could be an issue with the FTP package we use that we are aware of but seeing the commands filezilla sends will help.

Thank you for looking into it.

Here are the logs:

Hey @n8nonmac,

What does Filezilla do if you disable TLS support? Our node only supports plain FTP with no encryption, It looks to be PureFTPd as well so you might need to update your pure-ftpd.conf to include BrokenClientsCompatibility no

An alternative solution would be to use SFTP if it is enabled.

So yeah I checked with my host and none of those options are available to me. I’ll probably use an external service

I will get around to fixing this at some point it just isn’t a quick thing to resolve.
