Considering the current FileZilla-3.35.1 is current version...

Doubtful you can even connect to any new SFTP server with a version as old as yours.

The protocol mismatch will likely be to great to make a connection.

Because of the extremely old version you're using, the reported errors may be incorrect.

Upgrade FileZilla first, then retest your connection, post your results here.

Sorry but for Filezilla Server (not client)...
The latest stable version of FileZilla Server is 0.9.60.2
https://filezilla-project.org/download.php?type=server

You still probably should consider updating your version to see if the errors you're seeing have been fixed.

Reread my comment above.

FileZilla-0.9.60.2 is so old, likely it won't be able to connect to any system.

For example, your version is so old it may only support SSL2 + SSL3, both of which have been deprecated for years, so you'll get all sorts of connection errors.

Upgrade your FileZilla + retest + post your results here.

Your first step is upgrading FileZilla.

You're welcome to post your Windows Server IP so someone can test for an SFTP connection or you can do this yourself using nmap.

Refer to the nmap docs for more information about how to test for specific services.

Here's one way to test...

imac> sudo nmap -F 149.56.39.190
Password:
Starting Nmap 7.70 ( https://nmap.org ) at 2018-08-06 10:11 CDT
Nmap scan report for ip190.ip-149-56-39.net (149.56.39.190)
Host is up (0.052s latency).
Not shown: 96 closed ports
PORT    STATE    SERVICE
22/tcp  open     ssh
80/tcp  open     http
443/tcp open     https
445/tcp filtered microsoft-ds

Nmap done: 1 IP address (1 host up) scanned in 1.91 seconds

Open in new window


You should not see FTP, as FTP is insecure + very rarely will you find it running these days. Only people excited about being hacked repeatedly run FTP.

You should see port 22 open with sshd listening.

This might or might not means sshd is actually able to handle SFTP requests.

To find out for sure, upgrade your FileZilla + retest.

You can also setup a bogus SFTP user/pass + post it for people to test.

Then delete this user/pass after someone has verified your SFTP is working...

Or...

You can update your FileZilla + test...

David Favor:  Filezilla provides both client and server versions.  The client is at version 3.35.2.  The Server version which is the subject of this question is at version 0.9.60.2 as shown on this page: https://filezilla-project.org/download.php?type=server

Thanks Dave for mentioning this. I missed the detail about "server".

Likely next step. Post the IP where your FileZilla server is running.
