I have XGS 116 with 20.0.1 MR-1-Build342.
Using a MAC computer, gets the "File Import Error" error when connecting to VPN using Sophos Connect, the same config file is processed on the device with the windows operating system and it works smoothly.
I downloaded the installer and the config file from VPN Portal, here:
@Wellidy Almeida, SCC on Mac supports only IPsec, SSLVPN is not supported.
Thanks for your answer.
Guys of thecnical support told me that one solution is to use Tunnelblick client
