Well, it seems as though your client failed to authenticate. In order to root out one of the more common issues, we'll need to see your hosts file. Here's the steps to getting this file.

1) Press the Win + R key on your keyboard.

2) Paste the following into the prompt that opens: notepad %windir%\system32\drivers\etc\hosts

3) Use Ctrl+A to select everything in the file, then Ctrl+C into the textbox to post to this thread.

It's not a firewall thing, it has to do with what you are using to connect with your ip address, either ipv4 or ipv6. From what I've been told, it's likely that one direction is blocking the ipv6 traffic, using ipv4 instead preventing the connection from occurring. As such, you need to change the settings for your device or router to either block ipv6 traffic incoming and outgoing, or don't block either. How to do so, you'll probably need to google for your specific device/router.
