Hi guys,

 

Earlier I was able to connect to VPN but since past few days can't connect to the VPN and everything seems to be stuck. I have re-installed the app several times facing the same issue. My OS is Windows 11. I got the following error in GUI error log file-

[2026-02-23 00:39:28.6618173 UTC+05:30] [8344:6856] [guimessenger 238 error] failed to open shared memory. GLE=2

Hi, 

what is your FortiClient version? Try installing Forticlient 7.0 or later.

try looking at windows updates that have been installed lately and try uninstalling them and then check.
