Forticlient VPN keeps dropping randomly on Fibre connection

Hi,

We have numerous users who's Forticlient keeps dropping frequently on their home Fibre connections. I would just like to know, what would be the best logs, from the client side, to examine in order to help in getting to the root of the issue? I see there's different log levels like Emergency, Alert, Critical, Error, Warning, Notice, information, and Debug.

Please let me know what else i need to post here for more info?

Much thanks

Regards,
