May be you can not setup the Windows Firewall setting correctly.
Here is the tips for setting the Windows firewall for FTP protocol:

Add BestSyncApp.exe and BestSyncSvc.exe to the allowed list of the firewall.
Add Port 21 to the exception list of the firewall.
In FTP server side, select the transfer mode (Passive or Active), Passive mode is recommended.

If Passive Mode is used:
In FTP server side, set the port range used for the data channel.
Add this port rang to the allowed receiving port list of the firewall of the FTP server.
Add this port rang to the allowed sending port list of the firewall of the client (where BestSync is installed).

If Active Mode is used:
Set the port range in “Option”/”Active Mode” of BestSync.
Add this port rang to the allowed sending port list of the firewall of the FTP server.
Add this port rang to the allowed receiving port list of the firewall of the client (where BestSync is installed).

Please try to stop all the firewall and anti-virus software to see if BestSync can connect to the FTP server.
