3. Disable Windows Firewall
By default, the Windows Firewall program always enabled and it may prevent ongoing connections of any specific game or program to protect your computer from malware or online attacks. Now, if you think that the Windows Firewall program is troubling you somehow, make sure to temporarily disable it.
- Click on the Start Menu > Type Windows Firewall and click on Windows Defender Firewall from the search result.
- Now, click on Turn Windows Defender Firewall on or off from the left pane.
- Make sure to turn off both the Private and Public options > Click on OK.

- Click on Allow an app or feature through Windows Defender Firewall from the left pane.
- Now, click on Change settings > Go to Allow another app…
