Hi,
Has anyone had any luck using a Let's Encrypt certificate on the Sophos UTM for remote access under Cisco VPN (for iOS)?
Under 'Remote Access' / 'Cisco VPN Client' I can see and select under 'Server Certificate' setting.
But when I click 'Apply', I get this:
The certificate of the CA that issued the '<Let's Encrypt certificate name>' certificate is needed.
I've already tried importing all certificates under https://letsencrypt.org/certificates/ and https://www.identrust.com/dst-root-ca-x3
Let me know,
Model: Sophos SG125
Firmware version: 9.601-5
