openconnect pulse and 2fa

I want to use openconnect instead of pulsesecure/pulseUI to connect to my company's vpn.this was ok in the old server but in the new they have added 2FA.

I saw this https://stackoverflow.com/a/63232539/959179 which looks promising.

so I try a very basic test:

echo -e "${myPasswd}\n${freshOTPcode} | sudo openconnect --protocol=pulse --passwd-on-stdin -u me@company.com <vpn server>

    Connected to <ip_address>:443    SSL negotiation with <company vpn>    Connected to HTTPS on <company vpn>    Got HTTP response: HTTP/1.1 101 Switching Protocols    **Unhandled Pulse authentication packet, or authentication failure**    E [...]    **Failed to obtain WebVPN cookie**

I cannot make anything out of it . The PulseSecure v9.1R13 connects fine to the server.

the error is the same if I use the following arguments

echo "myPasswd" | sudo openconnect --protocol=pulse -u me@company.com --passwd-on-stdin --token-mode=totp --token-secret=813940 slovpn.aviatnet.com/external
