Hello,

 

I've install FortiClient on Ubuntu 22.04 LTS. (forticlient_7.0.7.0246_amd64.deb)

Found error message in /var/log/forticlient/sslvpn.log

Could not establish a VPN connection to VPN server.

20220915 00:27:35.818 [sslvpn:EROR] vpn_connection:463 socket error = Resource tempora rily unavailable (11) 

20220915 00:27:35.818 [sslvpn:EROR] vpn_connection:1402 Error: Can not connect to VPN server.

 

I would appreciate your help.

Regards,

 

FortiClient

    Check your /etc/resolv.conf for extra DNS resolvers that don't work.
