Please read about ALG, etc. here
Other (if the above doesn’t help):
are you an administrator on that device/PC?
or maybe the firewall is blocking filezilla from establishing a full connection ?
try using a VPN (or don’t use it if you’re currently using)
try downloading the latest version
and then create a connection and confirm all the certificates that pop up
btw. - where have you been for 7 years (your last post was 7 years ago) - in any case welcome back
