CSslvpnAgent::Initialize() 178 InitPipeHandle() failed

[andrejochemsen]

Hi all,

At our client we have one user who is not able to make a VPN connection. The client seems to connect until it reaches 90% and then goes back to 0.

Below i pasted a piece of log from the client. 

From Fortinet community there are some topics referencing the same kind of issue. Possible solutions include disabling IPv6 on the NIC, setting remoteauthtimeout 60 on the Firewall, reinstalling the Forticlient. All of which we have tried, but didnt solve the issue.

We use SSO for single signon. Devices are Entra joined. I can see in the Enterprise Application (in Azure) that authentication is succesfull.

The client version is 7.2.4.0972. From what i read in several topics this shouldnt be a troublesome version.

The only thing we didnt try is removing the software with the fcremoval.exe tool. We did however remove the client including the data from the appdata folders. What other opties do we have besides using the fcremoval tool (we have to get on site to use this tool in safemode, hence i post this here with the question if there are other possible solutions based on the log pasted below)...

Thanks in advance.
