AnyConnect clients randomly disconnect, reconnect

[hsoftcisco]

Hello,

We have been using our current configuration for some time, but recently most of the AnyConnect clients randomly loose connection, then reconnect. I have had the ISP and SonicWall look to see if they find any issue, but they do not. I have checked the event viewer on one XP machine and find numerous log entries regarding connection timeouts, etc. I have listed some below. A search of this comunity resulted in only one response that was incomplete.

This entry is listed as Error, Event ID 2, source is vpnagent:

Function: CHttpProbeAsync::OnOpenRequestComplete

File: .\IP\HttpProbeAsync.cpp

Line: 254

Invoked Function: CHttpSessionAsync::OnOpenRequestComplete

Return Code: -31522780 (0xFE1F0024)

Description: SOCKETTRANSPORT_ERROR_CONNECT_TIMEOUT

Another error:

Invoked Function: CNetEnvironment::testNetwork

Return Code: -28901363 (0xFE47000D)

This entry is a Warning:

Return Code: -27787250 (0xFE58000E)

Description: HTTP_PROBE_ASYNC_ERROR_CANNOT_CONNECT

HTTP (host: 198.210.1.1)

Another Warning:

Reconnect reason code 6:

Reconnecting due to the disruption of the VPN connection to the secure gateway.

There are numerous information logs referring to reconnecting, VPN connection re-established, primary SSL connection to the secure gateway is down.

Anyone have ideas on how to troubleshoot this?

Thank you for any suggestions.

Bill,

Were you able to diagnose why this issue was/is occuring? We are experiencing a similar issue with a user in our organization:

Hi,

Any solution to this.

Thank You

I have had the same issue. In my case Cisco client had conflicted with the old version of Forticlient. I've disabled Forticlient service and removed it from the on-boot applications. I do not have the problem anymore. I suppose this kind of issue can be also caused by some unexpected conflicts with other VPN clients too.

I hope this can help.
