We are using FortiGate firerwall(v7.2.5 build1517) and the FortiClient SSL VPN(v7.0.70345) on all our laptops, the problem is that the FortiClient VPN keeps on disconnecting even though the internet connection is available on the laptops. This is happening intermediately.
Can you please advise what could be the cause of this issue?
Can you link this issue to any change in your environment? Have you tested other devices/FortiClient versions? Is it possible for an effected user to use for a while web ssl portal instead of FCT tunnel mode? That should help to identify if the issue is on firewall or client side.
Check what is the impact on the CPU/mem before leaving it on for a long time. diagnose sniffer packet wan1 "host 18.104.22.168 and icmp" - this should keep putty/ssh sessions alive, that's the only reason is there. If you manage to capture the issue, submit the debug to Technical Support along with a firewall config backup and tac report.
I've been experiencing an problem with my FortiGate firewall (running v6.4.3) and FortiClient VPN (v6.4.0). The issue is that my VPN connection keeps dropping intermittently, despite having a stable internet connection on my devices. It's quite frustrating as it disrupts my work and remote access. I've checked my network stability, reviewed firewall settings, and ensured my VPN configuration is accurate.
We're encountering persistent disconnections with Forti Client SSL VPN (v7.0.70345) while maintaining an active internet connection on laptops. Despite internet availability, intermittent disruptions continue to arise. Our infrastructure, running FortiGate firewall (v7.2.5 build1517), is affected by this issue, requiring a solution to ensure stable VPN connectivity.
