Server Connectivity on Windows 10 is always "Blocked"

BoShakhat · Apr 21, 2023

Good Day,

Recently i have not been able to join any multiplayer game on Halo MCC , when i check the connectivity under gaming i get the below:

NAT Type: Open

Server connectivity: Blocked

I have tried all the steps in the support page, including setting the default profile for the firewall, updating windows, port forwarding for my router and checking the windows services, no luck.

I am using Windows 10.

Any clue on what to do next ? Thank you in advance.

:)

Hi, I hope you're doing great out there.

I'm Wille, an Independent advisor and I am here to help you with your concern.

The impact comes directly from NAT (Network Address Translate) ie the translation of network addresses from the ISP (Internet Service Provider). As well as the switching process between packets from your private network and the public network that your ISP dynamically provides for you.

Method 1

Reset connection profile in Windows:

1- Press the Windows+R keys, type Notepad and click OK;

2- Paste all the commands below:

@echo off

reg delete “HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings” /f

RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 8

RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 2

RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 1

RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 16

RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 32

RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 255

RunDll32.exe InetCpl.cpl,ClearMyTracksByProcess 4351

cmdkey.exe /list > “%TEMP%\List.txt”

findstr.exe /c:”target” “%TEMP%\List.txt” > “%TEMP%\tokensonly.txt”

FOR /F “tokens=1,2 delims= ” %%G IN (%TEMP%\tokensonly.txt) DO cmdkey.exe /delete:%%H

ipconfig /release

ipconfig /renew

ipconfig /flushdns

netsh winsock reset

net localgroup administrators localservice /add

exit

4- Name it ResetConnection.bat and click Save (save wherever you want);

5- Right-click on ResetConexao and select the Run as Administrator option;

6- Wait for the commands to process and restart the system and test.
