encountered VPN SSL agent error for no reason

Answered Question
Dec 28th, 2012

Hi,

Error message please refer to attachment.

If I am right, this may be caused by Internet Connection Sharing(ICS)  service as I used wired network share with my iPhone by creating  peer-to-peer wireless network at hotel, and before this, it was working normally all the time.

For now, I also can connect VPN successfully but the status always change to  "reconnecting" after 8 seconds and error message popup after several try.

I set ICS service as "manual" or  "disabled" and ensure it is not running, but not helpful.

OS: Win7 Pro x64 Sp1

AnyConnect VPN client Version:2.5.6005

Any reply would be much appreciated.

AnyConnect.

Thank you for your reply.

Already tried to reinstall but problem persist.

When I trying @hotel not @home, it is working now. So, I belive this may be impact with my home wireless router, I will continue to check the configuration, or if you have any suggestion for this?
