Hello ,

ikev2 mobile VPN randomly stopped working for all users .
When attempting to connect, im getting the below live logs:

Yes you should open a support case on this.

Hi @Yugal_R
Can you please check the cert that is installed onto the client PC(s.) If that has expired the firewall may regenerate a certificate to keep it current, but the only way to distribute it to your workstations would be via the ikev2 profile.

Try downloading a new IKEv2 profile, and installing it on one of your PCs. Do you see the same issue happening?

Hello @james.carson ,

I removed and downloaded and installed a new config file and place the rootca cert in the Trusted Root Certificate Authorities.

still the same error on the logs.

Maybe i should raise a ticket to support team

Kind regards,
