Check in Services if the service "FileZilla Server FTP server" is even running. Might not have started post-install or might be set to manual.

Setting up an FTP server may sound like a complicated undertaking only system administrators can handle, but it's actually quite easy and free with open source software FileZilla.

Also, if anyone has experience with a synology diskstation, that would be great too. Let me know what client you use to connect securely (FileZilla, CuteFTP, etc.). Thanks in advance!

After you connect your server with the client application like FileZilla, a free FTP application, the file is then edited back using a notepad or an IDE.
