Hello, there is a long thread in the Microsoft community talking of a similar problem with L2TP, that seems to have been solved, but my problem is with PPTP, as the integrated server doesn’t support L2TP.
With Windows 10 1909 version, everything works OK, I can connect from my laptop Windows 10 2004 updated till 2021-01 to my desktop, VPN server using PPTP.
But as soon as I update the desktop to 2004 or 20H2 and apply the latest updates KB4593438 (2020-12), KB4598242 (2021-01) and KB 4586876 (Net Framework 3.5 and 4.8), it doesn’t work. I initiate VPN connection from the same client (Windows 10 2021-01) to the “new” server and it doesn’t connect, it stays as “connecting to…” and finally error message “Connection interrupted with server… Might be due to Internet Latency or Server maximum capacity reached…”
Then, I restored the server to the previous 1909 version and it works again OK.
I also sent a feedback message using the “Feedback Center”. No answer yet.
I tried all the solutions proposed in the L2TP issue, uninstall and reinstall MiniWAN drivers, deleted and redefined the incoming connection, etc. etc. No way, it doesn’t work.
So, it seems that I will have to stay blocked with version 1909 in my VPN Integrated Server Desktop.
Any idea of help?
Any suggestion of solution will be VERY welcomed.
Thanks and best regards.
