What firewalls, if any, have you checked based on the comments here?
1 - Have you checked to see if your Windows 11 system has firewalls turned

2 - Is your Windows 11 PC a new system with it's own IP address?  And not
the same IP address as your previous PC? Generally how we do it here.  If
so, is there a network based firewall blocking access?
3 - Related to question 2, have you set anything in

If you go to the command prompt BEFORE running ftp and run ftp from the
command prompt and type use the debug option (like C:\Users\rob>ftp -d
myibmi) does that give you any information?
