  1. VPN connection Windows 10 2004 build 19041.423


    Hi

    I have a weird issue using a VPN, for some reason it wont work on my main machine ( version 2004 build 19041.423 ) The error message i get is this"Can't connect to VPNThe network connection between your computer and the VPN server could not be established because the remote server is not responding. This could be because of one of the network devices (e.g, firewalls, NAT, routers, etc) between your computer and the remote server is not configured to allow VPN connections."

    The things I have tested :


    • At first I thought it was a network issue , so i tried the set up the vpn with the same credentials on my crapy laptop and guess what , the vpn worked!!
    • Enable ports TCP 1723 , UDP 500 , 4500, still no luck.
    • Find "Xbox Live Networking Services" and disable that service. still no luck.
    • Open regedit, go to Equipo\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgent, change AssumeUDPEncapsulationContextOnSendRule value to 2. No luck.
    • I have a virtual machine configured on my main PC, it has windows 8.1 installed, I configured the vpn on it and it works !!!


    Any help will be appreciated

    :)

    Windows 10 apps not working on the Ethernet Windows 10 VPN internet connection

    Hi,



    Thank you for writing to Microsoft Community Forums.



    In order to assist you with the appropriate troubleshooting steps, please let us know:



    • Does this issue occur only with Microsoft apps?
    • Are you able to browse any website while connected to internet?
    • Which build version of Windows 10 is installed on the computer? To check type:
      winver in the search bar on the Taskbar and hit
      Enter.


    As you have mentioned that you are connected to internet with Ethernet via Windows VPN, I would suggest you try disconnecting VPN and see if you are able to access the applications.



    We await your response.



    Regards,

    Nikhar Khare

    VPN connection Windows 10 2004 build 19041.423

    No Internet Connection When VPN Is Connected

    This particular issue has been going on for almost a month now. My companies IT department is still trying to figure out the root cause. Below is a list of isolation / troubleshooting i've done.

    Issue: Once connected to the work VPN (successfully) the internet connection on the Windows 10 machine disconnects and does not allow any network traffic.

    OS: Windows 10 Home - Version: 1909 (OS Build 18363.476)

    Computer: Razor Blade 2019

    - Latest drivers installed

    - Latest Windows updates installed

    - System Wide issue

    Troubleshooting / Isolation

    • Cellular Data: Verified the Windows machine can connect to a hotspot and successfully browse the internet. (No VPN involved)

    • Cellular Data + Work VPN: Verified the Windows machine can connect to the hotspot & successfully connect to work VPN and successfully browse the internet.

    • Home WiFi: Verified Windows machine can connect to the home wifi network and successfully browse the internet (No VPN involved)

    • Home WiFi + Work VPN: Verified Windows machine can connect to home WiFi. It can successfully connect to work VPN. However once the work VPN is connected, the home WiFi network indicates (No Internet Access)

    • Ping Test + Work VPN: Verified I can successfully ping (work) websites and even the work VPN URL successfully without any packet loss. However once I go to ping (non-work) related addresses like google.com, apple.com etc. there is packet loss.

    At this point I decided to test my work VPN on my iPhone & Apple Mac.

    • iPhone: Home WiFi + Work VPN: Verified the iPhone successfully connects to home WiFi network and the work VPN and can successfully browse the internet.

    • Mac: Home WiFi + Work VPN: Verified the Mac successfully connects to home WiFi network and the work VPN and can successfully browse the internet.

    Isolated: Only the Windows machine seems to be affected. I even verified this issue occurs on multiple Windows user accounts on the Windows 10 machine.

    - Windows 10 is fully updated to the latest November Windows 10 update and issue persists

    - Deleted and Added the VPN configuration several times and issue persisted.

    Third Party VPN Client Test: Tested with Nord VPN and the Windows machine successfully connected to the home WiFi network & the Nord VPN connection successfully connected to a random server and successfully browsed the internet.

    - Disabled IPV6 on VPN & WiFi network configuration (Per IT Support guidance) and issue persisted

    *Currently updating to Windows 10 Insider Preview 19033.1 (vb_release) to see if this might fix anything pertaining to Windows 10 VPN.

    Thanks for any additional guidance / suggestions / help that the community offers.
