cisco anyconnect reconnecting after a short time then stays connected

Had an issue where cisco anyconnect would connect but then after a short time reconnect and stay connected for good then.

The issue was the ISP was blocking DTLS protocol. The anyconnect tries to use it as its better for voice etc, once it realizes it can't use it, it reconnects with it disabled.

Solution 1: Get your ISP to unblock it and get the benefits from DTLS. In my case I didn't have control of the ISP.

Solution 2 turn it off
under group policy for anyconnect profile
group-policy VPN-GRP-POL attributes
webvpn
anyconnect ssl dtls none
