Hacking Can't connect to Filezilla anymore

[SREGGOP]

I have connected my PS3 with Multiman to Filezilla on my laptop with Ethernet cable a dozen times and it always worked just fine.

Today it doesn't work, I haven't changed anything on my PS3, on my laptop the only thing I changed is I removed Avast antivirus and now use Windows Defender, but even when I turn the firewall off it still doesn't work.

Any ideas?

Thanks

EDIT: resolved it by changing my ethernet IPv4
