Performance Issues with EMS FortiVPN Client – Free Client Works Fine

Hello Community,

 

we have several employees experiencing severe performance issues with the Forti EMS Client 7.2.8, particularly when accessing internal websites via VPN and using applications like SAP GUI. In some cases, connections even drop unexpectedly.

Even after reinstalling the client, the problem persists. However, when switching to the free Forti VPN Client, the issues disappear immediately, and everything runs smoothly.

 

Our environment:
- In-house EMS Server 7.2.8 with FortiClient 7.2.8
--FortiGate connected via IPv4 only (IPv6 is disabled on WLAN and VPN adapters)
- Only SSL VPN is used; all other VPN options are disabled


Does anyone have an idea? Many thanks in advance!

Hi Leo

Are you using Web filter and/or app filter features? Can you try disable them temporarily just to see if they are causing the issue?

When you day "connections even drop unexpectedly", do you mean the connection to your application or the whole VPN connection?

    Hello AEK,

    we don't use WebFilter or other things. We use only SSL VPN and disabled all other things. 

    Not the VPN Client connection, i mean the connection to our internal applications. For example: Websites, Filesrv and SAP GUI to internal SAP Servers. The VPN connection is running and up.

     

    Thank you"!

    Can you try other versions on some test clients, like 7.2.7 and 7.4.3.
