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.

    Let me clarify my situation. This thread was opened due to problems with VPN L2TP connection.

    My problem does have two faces:

    1.- I found that Windows 10 VPN Server DOES NOT support native L2TP/IPSec protocol and I would need a 3rd. party product, what I don't want.

    2.- So, I need to use PPTP protocol, and THIS ONE is the one that when I install the 2004 or 20H2 characteristics update doesn't work, the integrated server doesn't accept the connection, that restoring to 1909 DOES work.,

    Then, what I would need is a solution for VPN connection to Windows 10 integrated server using PPTP in 2004 or 20H2 versions.

    Regards

    As I said in a previous post, I tried it and it didn't work :( and I also tried the referenced url's and they are reachable without any problem.

    But the VPN integrated server in my 20H2 still does NOT accept connections

    Thanks so much for your suggestion, but it didn't work either :( . I tried changing CurrentControl1 and CurrentControl and both at the same time, but it didn't work. :(

    So, restoring again PC with the VPN Integrated Server to 1909 where it works perfectly.

    Hoping anyone (even Microsoft!!!) could offer a working (for me at least) solution. If not I will have to stay in 1909 or might be wait till 21xx version

    Regards

    Try this. I have solve my problem.  I have tried many time on different version, that works.

    Run regedit

    HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\NlaSvc\Parameters\Internet

    Change the EnableActiveProbing to 0;

    （Sorry my English is poor.)

    ----------------------------------(google translate)--------

    1. After you log in with VPN, in an environment without internet, windows will automatically redirect to: www.msftconnecttest.com/redirect, and disconnect the VPN connection.
    2. If the VPN can access the Internet after logging in, the VPN will be normal after the windows redirect to www.msftconnecttest.com/redirect.
    3. This is why some people can log in to vpn and some people cannot log in.
    4. I have encountered this problem for more than a year. I have been using the ltsc version. Yesterday, after I tried to disable the redirection, the VPN became normal. I tried other versions of windows, which also solved the problem.

    you can try it.
