today we changed from a FG100D with 6.0.8 to a new FG100F and 6.2.5. Before we did not have any problems with all IPSec or SSL VPN connections. We have like 200 remote users becuase of of the Covid situation and last months like 50-60 IPSec connections via WAN1 and 50-70 SSL VPN connections via WAN2.
Today we changed also to SD WAN, also with the idea to put more traffic on WAN3 (mostly web traffic). Beisdes the SSL VPN connection is the SAME as on the FG100D model where everything went fine.
Today we got feedback from some users that their SSL VPN connection disconnected varios times after the change. I tried myself and my user and my ping didnt disconnect the whole time but at the same we connected via Teamviewer a 2-3 other users and they got disconnected like 2-3 times.
What can we do, is there a knoen bug about the SSL connection in 6.2.X?
