Cisco Anyconnect VPN client disconnects 1-2 seconds after connecting

Craddockc
Level 3
Level 3

Community,

I am experiencing an issue wherein several users attempt to connect to the VPN using anyconnect, it connects to the external IP on the firewall, prompts for credentials, and after entering their credentials it connects and then immediately disconnects. Our syslog server shows the following:

May 3 11:37:38 10.100.98.4 : %ASA-4-722041: TunnelGroup <DefaultWEBVPNGroup> GroupPolicy <CsrVPN> User <jgoggin> IP <38.x.x.66> No IPv6 address available for SVC connection

May 3 11:37:13 10.100.98.4 : %ASA-4-113019: Group = DefaultWEBVPNGroup, Username = jgoggin, IP = 38.x.x.66, Session disconnected. Session Type: AnyConnect-Parent, Duration: 0h:00m:02s, Bytes xmt: 10727, Bytes rcv: 3399, Reason: User Requested

May 3 11:37:28 10.100.98.4 : %ASA-4-113019: Group = DefaultWEBVPNGroup, Username = jgoggin, IP = 38.x.x.66, Session disconnected. Session Type: AnyConnect-Parent, Duration: 0h:00m:04s, Bytes xmt: 10727, Bytes rcv: 3399, Reason: User Requested

May 3 13:10:35 10.100.98.4 : %ASA-4-722041: TunnelGroup <DefaultWEBVPNGroup> GroupPolicy <CsrVPN> User <jhall> IP <38.116.28.66> No IPv6 address available for SVC connection

May 3 13:10:36 10.100.98.4 : %ASA-4-113019: Group = DefaultWEBVPNGroup, Username = jhall, IP = 38.x.x.66, Session disconnected. Session Type: AnyConnect-Parent, Duration: 0h:00m:03s, Bytes xmt: 10728, Bytes rcv: 3407, Reason: User Requested

May 3 15:07:58 10.100.98.4 : %ASA-4-113019: Group = DefaultWEBVPNGroup, Username = sdolan, IP = 38.x.x.66, Session disconnected. Session Type: AnyConnect-Parent, Duration: 0h:00m:04s, Bytes xmt: 10727, Bytes rcv: 3399, Reason: User Requested

Please notice that the duration of the tunnel is only a few seconds and that the Reason is "User requested" eventhough the anyconnect client disconnected automatically. I did notice that all the users who were having this issue were in the CsrVPN group. Users in other groups dont seem to be affected. Also, not all users in the CsrVPN group are having this issue, just a few.  If we move the user in Active Directory to a different Group Policy group, they can get on without issue. 

A couple of users who were having this issue (jgoggin above is one of them), all of a sudden were able to connect again "magically" after awhile.

Has anyone run into this before? Thanks.

Try to install DART and get diagnostics when the problem takes place

Mohammed,

Ive attached the DART files, one from a success and one from a failure. Please note that when I move the user from the DevVPN or CsrVPN group in AD to our PocVPN group it works. When I move the user back to either of the other 2 groups in AD it fails. Ive pasted below where the failure starts to occur. At this point I have no idea why group policy would cause this failure but it definitely seems to be related.

experiencing something similar, problem just cleared on its own.

any update on this?

Luis,

My issue also seems to be clearing on its own. I did go ahead and upload the latest Anyconnect images (4.4.x) for both Mac and Windows to my ASA's, forcing people to update the next time they connect to VPN. After the updates it seems to be working again for affected users. Still cant explain what caused it. 

I've got the same issue, I can connect using the client to one of my ASAs but noe the other, the one I cannot connect to is a new configuration, but both are running the same ASA version and use the same XML...  I've re-checked everything I can think of at least 3 times, the authentication says it's completed, but then it dies exactly the same way.

bpersonick,

Make sure the images that reside in the "Anyconnect Client Software" section of the ASA are the same versions that the clients are running. TAC found that the versions running on my clients weren't in this repository. They stated that this could cause clients to disconnect intermittently. After doing this, the problem slowly started to resolve itself for me. 

I think this would be a good practice. However, in environments that are running multiple different versions of the same operating system, it would be hard to find a version of the client that works with all the different clients, hardware, vendor, etc.
