Issue is not solved. I mean I can't connect to some servers I get this error and I can connect to different ones so that's confusing..
So I can't connect to the one I need....

How to I check in firewall btw?

My apologies, I was under the assumption your Issue was taken care of.

With the firewall, rather than allowing exceptions (for FileZilla), configuring Inbound & Outbound rules etc, try disabling It altogether. I'm just trying to establish whether It Is In fact your firewall that's blocking FileZilla's failure to authenticate with other servers. Also, are you running via a VPN or Proxy? If so, don't. See what happens thereafter.
