Hello together, a few months ago I was asking for help on how to set up a OpenConnect-based VPN-connection with Cisco Secure Desktop in Connman. Thanks to your great advices a friend made it work yesterday! Hereby the VPN connection is working perfectly, but just for a few hours. -------------------------------------------------------------------------- Unfortunately we still have this small error what will be easy for you guys to solve. The VPN connection is seriously working perfect in the beginning, but always a few hours later this error in /var/log/syslog occurs when trying to reconnect: "openconnect[1810]: Server certificate verify failed: signer not found" -------------------------------------------------------------------------- Hereby all approaches to reconnect the VPN fail. After creating a new cookie by... $ sudo openconnect --csd-wrapper=/home/user/.cisco/csd-wrapper.sh --authenticate --user <username> <hostname> ... and pasting this new cookie into /var/lib/connman-vpn/vpnname.config (overwriting the old one) the connection will work perfect for the next few hours until it fails again. -------------------------------------------------------------------------- I guess this error is more easy to retrace when reading this better formatted article on stackexchange: https://unix.stackexchange.com/a/464422/241507 Do you have any ideas about why this cookie has to be renewed all few hours? Is there any option on how to avoid this behavior? I would be very happy about your ideas! Thank you very much for your help! Dave
