Upgrade to Windows 10 2004 (VPN L2TP fail autoconnect)

Good evening.

After upgrading to Windows 10 2004, the L2TP / IPSEC VPN using MS-CHAPv2 with the option "Automatically use my Windows log-on name and password (and domain, if any) no longer connects automatically. Note that the computer in question is in an AD domain and in the previous version it was working without problems (the connection was established with the Windows credentials.

It turns out that now, in this version, it says that the user or password is wrong and shows the dialog window for entering the password. I put the same one I use for windows login and the connection is established. I wanted this to be done automatically and, if not possible, I would like to understand technically why this is happening.

Thank you.

Ricardo

    I reinstalled 20H2 on my laptop, and L2TP worked for a couple of days, and now again is not working.  I am totally baffled.

    SSTP VPN here. No issues since the November update. Tried with both 2004 and 20H2.

    L2TP VPN here, literally just applied the KB here https://support.microsoft.com/en-us/help/4592438/windows-10-update-kb4592438, and I can confirm this is now resolved for me - after a year of waiting! :)

    No way, no luck.

    I tried again to install 20H2, VPN with PPTP doesn't work.

    Tried to install KB4592438, answer was "already installed in the system".

    Windows version is 19042.685

    Looked for new updates, the only one is KB4586876, a Net.Framework one.

    Uninstalled all the WAN Miniport drivers, deleted the input connection, restarted the system, the WAN Miniport drivers where newly installed, I redefined the input connection, but the problem is still there.

    I tries to connect VPN with PPTP again and it didn't connect, message was "network connection was interrupted with the VPN Server".

    So, system downgraded again to 1909 compilation.

    Any idea of help will be appreciated

    Regards
