VPN Client disconnects after one hour

Hello,

I ran into a problem with remote access VPN.

The connection can be established successfully and the ressources are available, but exactly after one hour the client disconnects with the error message "Failed to renew encryption keys".

In ike.elg it looks like phase 2 is failing, but everything is fine at the initial connection.

I checked and changed several lease times and renegotiation times, the client still disconnects after one hour.

I already have a service request open since three weeks now with no solution.

Did anyone experience this before?

This is a classic case. Please make sure CRL on the Management is available through VPN or is not encrypted.

How can I check these parameters? (I am kinda new to Check Point)

Are you using certificates for authentication?

Re: VPN Client disconnects after one hour

There are no certificates for the clients, but a SSL certificate for the gateway. So the clients connect to the domain-name and not to the IP of the gateway. But I also tried to connect to the IP and got the same error.

For authentication I am using Identity Awareness with AD-Query and local configured users. The error occurs on both of them.

More information to the gateway - it's a stand-alone solution on R80.20 and Endpoint Security E80.92.
