You need to provide a suitable --csd-wrapper argument.
Failed to obtain WebVPN cookieI tried --no-xmlpost post and got error as well.
Here is some background:
I had Ubuntu 14.04 and was connecting to vpn server using openconnect. Then a week ago, it stopped working with this issue. My guess is that the vpn site upgraded its Cisco vpn server to required to CSD trojan. Anyhow, I decided to upgrade to 16.04 and still have the same problem.

I found my answer through this post:
I did the following:
cd ~
mkdir .cisco
cd .cisco
wget
chmod +x csd-wrapper.sh Edit the file with the vpn server:
CSD_HOSTNAME=vpnserver.com Run the file
./csd-wrapper.sh Run openconnect:
sudo openconnect --csd-user=YOURLINUXUSERNAME --csd-wrapper=/home/YOURLINUXUSERNAME/.cisco/csd-wrapper.sh vpnserver.com I found that I needed to specify --os=win as well. This seemed to work around a 404 response that the server was generating when attempting to download sfinst.
GET
Got HTTP response: HTTP/1.1 404 Not Found (does not exist)Information on the 404 for sfinst issue can be found on the openconnect-devel mailing list "Connecting with Linux when the CSD is available" post.
I had success with the following command which uses the os flag and the csd-wrapper flag together:
sudo openconnect \ --user <USERNAME> \ --cert-expire-warning=15 \ --certificate <CERTFILE> \ --os=win \ --csd-user=<USERNAME> \ --csd-wrapper=<PATHTO>/csd-wrapper.sh \ e.g., vpn.company.com>I had this Error in Ubuntu 18.04
I was able to connect to the server using the link below and the second answer.
just use the -v flag
sudo openconnect -v NAMESERVER.COM
