We have a SSL Gateway setup with the anyconnect client.
We have picked up on some of the Windows 7 Tablets that you can install via the web page.
Once installed you are connected to the network.
However once you disconnect, and try with the anyconnect client u get the following error;
" Anyconnect was not able to establish a connection to the specified
secure gateway. Please try connecting again"
We have not seen this on any of the Windows 7 laptops nor Windows XP.
The URL have been added to the trusted zones.
We have gone as far to disable anti-virus / windows firewall
Disabled the "Protected mode" with in internet explorer.
Anyconnect client version 2.5.3055
ASA 5510 Serial number JMX1504L05Y - ver asa841-k8
Please try to disable UAC and check again. Also is the ASA's certificate issued by some trusted third party or is it a self signed certificate? If its self-signed , please try to install the ASA's certificate in trusted root cerficate authority store.
Once done, try to connect again. Otherwise we would need to collect DART logs to check for the issue.
