I have upgraded my firewalls to 8.3 and subsequently upgraded my AnyConnect to 2.5.2xxx
All seems good, except some PCs can't use the AnyConnect anymore.
The client will connect, and gets an ip address, but then drops the connection immediately, showing messages:
"The VPN client driver has encountered an error"
"AnyConnect was not able to establish a connection to the specified gateway, Please try connecting again"
and then at the bottom of the AC window:
"No trusted network detection rules defined. Contact your network admin"
But I have created a profile with trusted network rules set to Connect. I can see the profile is downloaded when the client attempts connection, and is stored in app support, and AC finds it during the connection but then the event manager logs indicate it's not being used, "No profile available for host xxxxxxxxx.com", that some default profile is being used, which has "TrustedNetworkPolicy:disconnect" set.
I've also found out that the IPsec client won't work on this pc either, says the virtual adapter was not recognised by the operating system and fails to enable
Thanks for reading
