"An established connection was aborted by the software in your host machine"

Hey!
It's probably a stupid question but I hope someone might help me. So I'm trying to connect to my ftp-site via SmartFTP as usual, and out of nowhere I cannot and the information goes as follows:

[18:38:57] SmartFTP v2.0.997.4
[18:38:58] Resolving host name "ftp.xx.xxx.com"
[18:38:58] Connecting to xxx.xxx.xx.xx Port: 21
[18:38:58] Connected to ftp.xx.xxx.com.
[18:38:58] An established connection was aborted by the software in your host machine.

What should I make of this? I have not downloaded any new software to my computer lately... What could be the problem?
I would be so grateful if anyone knew what the problem could be.

Hello ..

1. Install the latest version of SmartFTP from:
https://www.smartftp.com/download

2. Post the complete log without removing the host name.
