IPsec Client VPN Certificate problem

Wisam Mouslli

Hi there,

Our IPsec VPN Client was working fine but suddenly it stopped working giving this error 'Filed to established child SA' knowing that the SSL client VPN is working fine.

In the Admin page of Sophos VPN it says ''undefined'  remote certificate has expired or is not yet valid' I need explanation and guidance please on how to deal with the certificate or how to create one if required and link it there and what type of "local" and "remote" certificates I should choose.

Thanks.

    Hello Wisam,

    Thank you for the screenshot, I thought you mentioned you were seeing this in the Sophos Connect configuration page in the XG firewall, but please clarify.

    Please check the OpenVPN Log in the client and the charong.log and strongswan.log on the XG at the moment the client tries to connect.

    And in the Sophos Connect configuration for Authentication Type are you using Preshared Key or Digital Certificate?

    Regards,
