NPPFTP unable to connect

tfcroft4

I have a laptop and PC, both with windows 10 both with NP++ and NPPftp plugin ( v 7.7 32 bit ) on a home network.
Laptop with NPPftp works fine
PC has stopped getting a connection with the following log:
[NppFTP] Everything initialized
-> TYPE I
Connecting
-> Quit
Unable to connect

I can get a FTP connection using my Browser and FileZilla

( I did disable Windows Firewall too but that did not make a difference)
{i did uninstall and re install NPP too but no change.)

I deduce that this must be a specific Windows 10 setting problem rather then software or network.

Can any one make a suggestion of any setting that may now be preventing the connection?

Update
I have also tested using a ftp server on ftp://localhost - again no connection via NPFTP but can connect using a browser.
Thanks
