multiple requests for a session

Hello,

While checking, it is seen that when an sslvpn client (using forticlient 6.0.6) starts a vpn request via the fortigate firewall towards the authentication(radius) server , instead of one there are two or sometimes three requests seen.

eg. as below.

10.0.58.55  is the fortigate firewall & 10.1.4.21 is the authentication server.

4.355284 port3 out 10.0.58.55.12039 -> 10.1.4.21.1812: udp 126 9.360274 port3 out 10.0.58.55.12039 -> 10.1.4.21.1812: udp 126

Please assist. thanks.
