Under the server's Events/System Logs we have the following error appearing:</P><P></P><P>"A request was received with an authenticator that is not valid from client Cisco VPN 3000."</P><P></P><P>We seem to get 3-4 errors after every successful authentication. I'm beginning to suspect it's client related (v3.6.3) since the errors don't appear when I "test" the authentication from the VPN admin webpage. Everything seems to work fine, I just don't know if this is an issue or not.</P> Fri, 21 Feb 2020 18:06:39 GMT https://community.cisco.com/t5/network-access-control/error-messages-in-system-log-of-ias-server-during-vpn/m-p/193981#M6210 dsiwa 2020-02-21T18:06:39Z Re: Error messages in System log of IAS server during VPN authen https://community.cisco.com/t5/network-access-control/error-messages-in-system-log-of-ias-server-during-vpn/m-p/193982#M6211 <HTML><HEAD></HEAD><BODY><P>It sounds like a client issue.
