Software showing "Firewall Blocked"
4.5
The network firewall is preventing the app from sending or receiving data.
Symptoms
- "Connection Refused"
- No internet in app
- UAC prompt
Possible Causes
- Strict firewall rules
- App not whitelisted
- Public network restrictions
Step-by-Step Fix
1
Allow through Firewall
Go to Control Panel > System and Security > Windows Defender Firewall > Allow an app.
2
Switch to Private Network
Firewalls are more restrictive on "Public" WiFi networks.
3
Check Router Firewall
Ensure your hardware firewall isn't blocking the app's ports.
When to See a Technician
Some apps require specific "Ports" to be open (e.g., Port 80 for web, 443 for secure).
