Allowing Apps Through Windows Firewall After Network Connection Failure

1. Open Windows Security

Press Start → type Windows Security → open it.

2. Go to Firewall & Network Protection

In the left panel, select Firewall & network protection.

3. Choose “Allow an app through firewall”

Scroll down and click Allow an app through firewall.

4. Modify Settings

Click Change settings (you may need administrator rights).

5. Find Your Application

Scroll through the list to locate your app.

If it’s not listed, click Allow another app… and browse for the executable file.

6. Enable Access

Check the boxes for Private and/or Public networks depending on where you want the app to connect.

Click OK to save changes.

Important Notes

• Private network = trusted networks like home or office Wi-Fi.

• Public network = less secure networks like coffee shops or airports.

• Only allow apps you trust, since opening firewall access can expose your system to risks

If Connection Still Fails

• Check Network Profile: Make sure your PC is set to the correct network type (Private vs Public).

• Reset Firewall Rules: In Firewall & network protection, choose Restore defaults if rules are corrupted.

• Check Third-Party Security Software: Antivirus suites often block apps separately from Windows Firewall.

• Run Network Troubleshooter:

Press Start → type Troubleshoot settings → select Internet Connections → run the troubleshooter.

• Verify Proxy/VPN Settings: Misconfigured proxies or VPNs can block access even if the firewall allows it.

• Some network errors occur when your device cannot resolve our official website's domain name. To fix this, try changing your system's DNS server to one of the following public DNS addresses:

- DNS: 223.5.5.5 or 223.6.6.6

- DNS: 8.8.8.8 or 8.8.4.4
