FortiClient Random disconnects

Hi all,

I am encountering an issue with my FortiClient VPN where I am intermittently disconnected. This problem seems to occur randomly; sometimes I can remain connected for 2 to 3 hours without any issues, while other times I am disconnected every few minutes. I have attempted to connect using different ISPs, including LTE and various fibre providers, but the problem persists. It's worth noting that I am only making use of the client and not the EMS.

Currently, I am using version 7.2.2 of FortiClient, while the remote FortiGate is on version 7.2.7. Additionally, I do not use any other VPN software or client.

In an effort to troubleshoot, I have enabled debugging on the client and observed the following output when the connection drops:

If anyone has encountered similar challenges previously, I would be grateful for any insights into what might be causing these connection drops.

Any feedback or suggestions would be highly valued.

Hi @Toastvader,

To better understand the logs, please refer to https://community.fortinet.com/t5/FortiClient/Technical-Tip-Interpreting-WSAGetLastError-in-FortiClient-Debug/ta-p/191800

When did the issue start? Was there any changes such as a Windows update before the issue start? Does it happen to other users?

Hi HBAC/Anthony_E ,

Our system admin recently implemented some changes to boost our security measures. These alterations included updates to our security policies and the addition of endpoint monitoring applications on our devices.

It seems myself and one other user, out of our group of 12, are experiencing disconnects. The only common factor we've found is that we're using the same laptop model.

Thank you for the information provided. I'll investigate further on my end and discuss this matter with our system admin.
