Hello @JaCh0o,

Let's try something and see if it makes a difference:

1. Go to Network Adapters tab and set the network type to Home/Office using the drop-down menu near its name

2. Then, from the same Firewall Tab, click on Settings from the top-right , then, for the network you're currently connected to, uncheck the stealth mode button to disable it.

If the issue persists, go to Firewall and choose the Rules tab. Reset Rules. Restart Windows and check if the issue is resolved. In the event the traffic is still being blocked, check for other security solutions and firewall programs and uninstall them, if any. Restart Windows and check again.

If the above steps don't work, then I would also advise to get in touch with one of our engineers for a remote session, if necessary.

Let us know how it goes.

Regards
