Is KB5026372 causing an issue with VPN connections?

We have a number of users that have had recent updates of KB5026372 and this has seemingly stopped their VPNs from connecting (loses connection instantly as soon as VPN connected, no more internet access), we use L2TP/IPsec with pre shared key. We have troubleshooted this with the network team, but nothing has changed and they are confident its not an issue caused by us. I have uninstalled KB5026372 on my machine, which had the issue also and then VPN works. Issue we have here is that our updates are handled automatically and it will pull down the updates again and install. Only solution is to pause updates for a set period of time in the hope that this gets resolved in a future update.

Has anyone else reported these issues? I have seen a few articles online regarding this and slowness of some VPNs after the update (which i had before it eventually just stopped working), but no solution other than uninstall.

Hello! My name is Mostafa, and I will try my best to assist you with this so that you find a satisfactory solution.

I’m sorry that you are experiencing this issue. Yes, many users have been reports of VPN connection issues after installing KB5026372. The update is causing problems with VPN connections, especially L2TP/IPSec VPNs.

If your updates are handled automatically, and it will pull down the updates again and install, you can pause updates for a set period in the hope that this gets resolved in a future update.

Go to Settings > Update & Security > Windows Update to pause Windows Update. You can click Pause updates for seven days to block updates for a week; extending this time by clicking again later is possible.

Review the below article.

If the above steps do not help, reach out to me, and I will be happy to help and try my best to resolve your issue. Thank you.

Best,

Mostafa

    I don't understand this. it is a MAJOR problem for many companies I'm working with. and they are holding off updates because of it.

    My computer automatically updated yesterday, which reinstalled the may update, broke my VPN again, then installed the June update so NOW uninstalling the May update is not even an option.

    this is just terrible!!

    the running joke is that Microsoft is doing this intentionally to push companies to use Azure cloud services............ I know it's a joke, but i'm starting to wonder.......

    June 15th and still a issue even after the CU 06 updates rolled out this week. We are now going to have to pause updates for maybe 3 months.

    Installed KB5027231 today as no longer being prompted to install KB5026372, and I had the same issue so I have had to uninstall this latest one. What I have discovered when testing is if I connect by device via the hotspot on my mobile phone to a different provider, it is ok, but not when I go via my home broadband provider.

    I couldn't find the PackageName but I've disabled the windows update service for now.

    This also means I won't get defender updates. :-(
