Earlier today the messages said that the FTP Host name HAD been resolved to a particular IP address with a 21 port.
After 15 to 20 minutes of trying I now get messages like this as I just tried again.
Every single credential works perfectly in FileZilla.
So what if you replace the ftp server address with the actual IP - do you get the same error?
Send me your ftp and account details in a personal message so that i can test what you are doing.
From FileZilla
Resolving address of wpxxxxxxx.server-he.de

So please:
Are you hosting with IONOS by some chance?
Brad, the Nodejs FTP connection test issue has been fixed. This is non-related.
Not by any chance. I have 2 IONOS accounts but this is HostEurope.
It's not fixed for a PHP site. Thought it might be related. Still can't use my IONOS hosting without Filezilla. Sorry, thought it might be related. I'll shut up now. 
Brad, if you have specific issue with FTP connection, post a separate topic and explain it there!
The error reported in the first post of this topic was caused by wrongly entered ftp server address in Wappler target configuration.
