+### Windows Firewall
+
+On Windows, the firewall cound be an issue. Try this:
+
+**Quick test first — temporarily disable firewall**
+If your phone can connect after disabling it, the firewall is confirmed as the cause.
+
+**Proper fix — add a firewall rule (run PowerShell as Admin):**
+```powershell
+New-NetFirewallRule -DisplayName "Dev Server 1420" -Direction Inbound -Protocol TCP -LocalPort 1420 -Action Allow
+```
+
+**Or via GUI:**
+1. Search → "Windows Defender Firewall with Advanced Security"
+2. Inbound Rules → New Rule
+3. Port → TCP → 1420 → Allow → All profiles → Save
+
+**Also check if Windows marked your network as Public** (Public networks block most inbound connections):
+
+```powershell
+# Check current network profile
+Get-NetConnectionProfile
+```
+If `NetworkCategory` shows `Public`, change it to `Private`:
+```powershell
+Set-NetConnectionProfile -Name "YOUR_NETWORK_NAME" -NetworkCategory Private
+```
+
+**Verify the port is actually listening on 0.0.0.0:**
+```powershell
+netstat -an | findstr 1420
+```
+You want to see `0.0.0.0:1420` — if it shows `127.0.0.1:1420` the server binding is still the problem.
