Hi All,

we are getting below “Untrusted Server” error while connecting to VPN gateway cisco ASA Gateways via iOS Devices! But when they trust , they are able to login. 

ASA version: 9.8(4)15

ASDM: 7.8(2)

ASA 5516

Hi,

You receive this error if the device does not trust the certificate you are using on the ASA. If you don’t already, get a certificate issued by a public Certifcate Authority and install this on the ASA. Most devices will trust the public CAs by default, so therefore you should not receive the warning again.

Also Ensure the certificate is issued to the FQDN and the users connect using the FQDN and not the IP address, otherwise you’d receive an error also.

HTH
