Please let me know in the comments below if this affected you. I have no idea how widespread this problem is. Shown below are screenshots that capture the steps I followed to prevent the update from being reinstalled: My Environment To ensure it remains available on the web somewhere into the future, I'll also make it available here: The utility is apparently no longer available from its original home at Microsoft. The link above includes a downloadable copy of the Windows Update Show/Hide utility from Microsoft. I followed the instructions here: How to Hide or Show Windows Updates in Windows 10. This was not a sustainable situation, so I set about preventing the KB5018410 update from installing again. Blocking the Windows Update from Reinstalling I uninstalled the Windows Update (again), rebooted my computer (again), and then confirmed that FortiClient VPN was working (again). KB5018410 was back! And, once again, it broke my FortiClient VPN. When I came in the next morning, my computer had rebooted again overnight. To uninstall the update, I went to Control Panel > Programs > Programs and Features > Installed Updatesįollowing the restart, I was able to successfully connect once again: Deja Vu All Over Again I checked my recent updates and found what turned out to be the culprit: KB5018410. This was all the confirmation I needed that the Windows Update was the source of this newfound error.

At least until his FortiClient VPN required a reboot (probably because it detected a pending Windows Update).at which point Windows installed updates.and following said reboot.he was also unable to connect. I then checked with a colleague to see if he could connect to their VPN. I reached out to our client to see if they had made any recent changes to their VPN server. Confirm No Changes Made to the VPN Server Satisfied there was nothing more I could do with my VPN client utility, I moved on to the next troubleshooting step. I ran the Online Updater utility, but all it did was confirm that, yes, I did have the latest version of FortiClient VPN: So, I went to the FortiClient VPN download page and downloaded their automatic updater. It doesn't even say when it performed its last update check. It said 'latest version', but for all I know it's been saying that for months. (-5) Checking FortiClient VPN for Updatesīefore uninstalling Windows security updates, I checked to make sure I had the latest version of the FortiClient VPN client utility.

The server you want to connect to requests identification, please choose a certificate and try again. I got the following warning message when trying to connect to one of my clients via the FortiClient VPN: Warning
