VPN fails with "Did not find interface for local_gwy"

[Stephen3]

A couple of Windows 11 users have trouble connecting to VPN using FortiClient 7.2.2.0864.  The error in the logs is:

FortiSslvpn: 27792: Did not find interface for local_gwy

KB2693643 is not installed nor are any of the Windows optional features for RSAT.

Hi @Stephen3 

Have you tried uninstall/install it again on these end users ,you may run the below debug commands on FGT cli to get more detail info:

diag debug enable

diag debug console timestamp enable

diag deb application fnbamd -1

diag debug app sslvpn -1 

If this FCT it is licensed l would suggest to open an ticket in order check the issue why its failing.

Hi @Stephen3, 

That error message indicates a client side issue. Have you tried ethernet and WiFi? Both doesn't work? You can also try a different FortiClient version.

We're using the free version of FortiClient, so it seems that I can't ask support when it doesn't work.

Is there anything more useful than "your users' laptops/network/internet must not work right" that we can look at?  The VPN works just fine for some users, so it shouldn't be a config issue.

Edit: User reports no issues with Cisco AnyConnect VPN from the same system... so it's unlikely to be their network or laptop that is the problem.

Hi @Stephen3,

Try disable IPv6 on ssl virtual nic card and see.
