Problem with security update KB5040430

Question

I recently installed the KB5040430 security update for Windows Server 2019, from that moment the Hamachi VPN client (2.3.0.111) disappeared, I did a reinstall but it didn't work, until I uninstalled the KB5040430 security update and reinstalled the Hamachi VPN client, I had it again. Is there any solution.?&nbsp;

Hi CDGlez,

I've reviewed the Microsoft release notes and I do not see anything mentioned that would cause this, you may want to check if it is changing any settings in your Windows firewall. I would recommend enabling logging in Hamachi to see if that captures any useful information.
