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

    Just to check, did you start the service manually and then set to automatic start? I noticed seeing to automatic and just restarting didn't make the service start after the restart for some reason.

    I enabled it and set it to start "Automatically" but it didn't seem to start after logon. I went back in and changed that to "Delayed Start" and it's worked at least 10 times in a row (after each reboot)... just need to wait a bit after logging on. That was all on one laptop though.

    Thanks everyone! And good luck!
