vpn user gets disconnected at 1.00am

one of my user discovered that his vpn connection get disconnected at 1.00am.

he uses the forticlient ssl vpn connection method.

after he gets disconnected, he has trouble getting connected back again.

it so happens that we configured the sent logs to analyzer from firewall at 1.00am.

does transferring of logs from firewall to analyzer causes ssl vpn to get disconnected ???
