Hi, I want to connect to cisco-compatible anyconnect vpn from Yosemite OSX 10.10.4. I installed openconnect using "brew install openconnect?. When I connect to the vpn server using sudo openconnect -v ?user=<uname> 196.1.111.161 The following happens POST https://196.1.111.161/ Attempting to connect to server 196.1.111.161:443 SSL negotiation with 196.1.111.161 Server certificate verify failed: signer not found Certificate from VPN server "196.1.111.161" failed verification.
