You have not given me the IP to narrow it down to know if this is your IP address. (feel free to send it privately), but assuming I have the right IP address, Since this is NOT FTP... I doubt this is your IP. The app never sends a single FTP packet out over the wire. I've tried it Several different ways, bypassing firewalls and connecting directly to COX communications modem, and directly through Starlink. ALL firewall blocking is shut off on the Windows 10 box. Please give me the IP so I can filter on that. Then we can see if ANY packet even goes out.
Here is a rejection that is HTTP and says forbidden.
