AnyConnect VPN stopped working

[S.ashok S]

Hi,

My AnyConnect VPN was working fine till Yesterday and stopped working. Showing the below error

"The AnyConnect client service is not responding. A VPN connection cannot be established. Contact your system administrator."

All users are getting the same error.

Uninstalled and reinstalled client and also tried with other VPN client but no use.

Even configured the new TEST anyconnect VPN but getting the same error. 

Kindly help to resolve the issue.

Attachment is the log while connecting the VPN.

Thanks and regards,

Ashok

If there have been no other changes, are you able to give your ASA a reboot?

Which ASA do you have, and what software version is on it?

Hi,

We have rebooted the device couple of times but no use.

Kindly find the device details as below:

Model: ASA 5525

Version:9.2(2)4

Thanks and regards,

Hi,

Thank you for your reply.

The issue was with certificate in ASA.

I have removed old certificate and reconfigured the certificate with CN=X.X.X.X (public IP address) instead of domain name.

Thanks and regards,

Ashok
