AnyConnect VPN Client on IOS Router

Hi Guys, I configured AnyConnect SSL VPN on Cisco 2811 router. It works perfectly when I login via web and run secure mobility client. However, when I connect directly from the mobility client connection fails. It does not even ask me for username and password.

I have not figured out yet, why mobility client works when launched from the web and why it does not work directly. Any input or hints would be much appreciated

Looks like you might have been affected by bugID: CSCty90942:

Standalone Anyconnect 3.0.4+ fails to connect on IOS 15.x & 12.4T

Workaround:
[1]Use web-launch
[2]Downgrade it to 3.0.4236 or main release of 2.5.3055
[3]The fix is availble on MR10 and later 3.0, 3.0.1xxxx...upgrade the package
and client.

NOTE: If upgrading to AC versions of 3.0.10057 or 3.1.01065 or higher does not entirely resolve issue and continue failing the standalone client connection due to same "server returned an invalid or unrecognized response" error message, try upgrading IOS code as well to 15.1(4)M5 or higher for compatibility between the AC client & IOS router versions.

I tried downgrading the anyconnect client and server down to 2.5 , but it didn't help. Tried it in GNS on 7200 router, but I see the same results there. It seems that generally Standalone Anyconnect does not work on IOS Routers without web authentication.

I finally managed to upgrade the router to latest IOS version 15.1(4)M6. It resolved the issue with the direct connection from client. NOw everything works like a charm.

Thank you all for your time and support ! I appreiate it.
