Losing connection with Unknown DTLS packet

[Stuart Luppescu]

Hello all, Recently I've been losing my VPN connection with many
messages like this in the console:

Unknown DTLS packet type 0b, len 1
Unknown DTLS packet type 0b, len 1
Unknown DTLS packet type f6, len 1
Unknown DTLS packet type 0b, len 1
Unknown DTLS packet type 76, len 1

Unknown DTLS packet type 76, len 1
Unknown DTLS packet type 0b, len 1
Unknown DTLS packet type 0b, len 1
Unknown DTLS packet type 0b, len 1

I'm running openconnect 7.07 on a Gentoo Linux system.

Any idea how to fix this?
