Issues with SSL VPN, disconnect after a few minutes

Hello everyone,
I have an issue with my USG FLEX 200. I've setup the SSL VPN, everything works fine when I'm connected with secuextender.
But after a few minutes, I get disconnected, here is the logs after the few minutes when it starts to go wrong :

Hi @mlaur47,

The issue is the same as the following post, and the fix is already included in the latest firmware version. Make sure your USG FLEX 200 is upgraded to the latest firmware version and Windows SSL VPN client is 4.0.4.0. If the issue still exists, please send the remote access of the USG FLEX 200 and one SSL VPN account to me in private message.
