I'm having some problems to maintain my VPN connection using FortiClient 6.0.2. This VPN is from a company and some users does not have this problem.
The log only shows this when the VPN is disconnected:

I don't know if is something on my side or in the company side. On the FortiClient forum they have a similar problem and the problem was solved changing the users to IPSec:
I had this exact same issue with SSLVPN for my company. Constant disconnections every 2-10 minutes at random for all users. The only fix I could come up with was to switch everyone over to IPSec. Holds solid and never drops.
But before contact the company about my problem, I would like to understand and have more information about what's happening.
