Hello,

Today I updated Windows 11 to the new version (22H2) on 2 PCs. FortiClient VPN worked seamlessly on the previous version (21H2) but after the update it doesn't connect and gives the following message:

Is it a known issue with FortiClient VPN? Is there a solution?

Thank you in advance,

I removed and then installed the network card from device manager (plus I removed I think TAP Windows Adapter), removed/install Forticlient VPN and it worked

Windows 11 has been updated to a new version (22H2) which version is Forticlient for?

Hi Everyone. My issue is a little different in that my FortiClient shows that it is connected, and I even get an IP address, but I cannot ping anything inside my network. I just get "PING: transmit failed. General failure." Here are screen grabs of my FortiClient and Windows versions:

Reinstalling FortiClient latest version and rebooting did not make any difference. If anyone have a fix it would be appreciated. I really do not want to reinstall everything form scratch.

I neglected to mention that it does the same, whether I am on Wi-Fi or LAN, so it is not a driver issue.

The issue is usually due to network connection. - Check whether the PC is able to access the internet and reach VPN server on necessary port. - Check whether correct remote Gateway and port is configured in FortiClient settings.

I have this same issue, the VPN connects just fine but the IP never updates and using the work around to manually configure the Network connections is the only way to get it to work. There is no issue with the network, I have tried in numerous locations and it seems to be consistent with just the one PC with Windows 11. Everyone else in the company has no issues connecting to the VPN. Everything is configured properly so its not network, in an effort to try and figure out if its an issue with my profile I reinstalled windows 11 and the issue remains.

I have been researching and digging into this for a while and stumbled on the solution you need to uninstall (KB2693643), just did it on my machine and FortiClient connected with no issue.

Wow!! James, I don't know where you found that, but you nailed it!!!! I had the same problem (Forticlient 7.0.7.0345, Windows 11 22H2:( Forticlient shows "Connected" and a valid IP address given via DHCP, however you cannot access anything on the corporate network, since your Fortinet SSL VPN Virtual Ethernet Adapter, actually gets an automatic IP (APIPA, 169.254.x.x) and not the one informed by Forticlient. I had already realized that forcing a fixed IP manually, plus mask and DNS on the Fortinet SSL VPN Virtual Adapter was a working workaround, but I was still trying different things everyday for the last 2 or 3 weeks to try to find a definitive solution. And the uninstall of KB2693643 was the only thing that really WORKED, and I tested it succesfully on the 3 computers where we were having this problem!! I did it easily with command "wusa /uninstall /kb:2693643" on the Command Prompt (opened as Admin). It just will pop up for a "Yes" to confirm. Then I didn't even need to restart. I tested the VPN connection again and it worked. On the other hand, I've seen that this patch is RSAT (Remote Server Admin Tools). In 2 of the computers with this problem, I am pretty sure that RSAT was installed, but the third one, no way, cause it was a regular user computer. Anyway, I won't worry that much and enjoy that it is fixed now. Thanks a million!!!!
