I just purchased an AnyConnect Essentials VPN License for my ASA 5505. I had to upgrade to ASA 8.2.
Now that I have upgraded and installed the license, the AnyConnect client will no longer connect. It gives the following error: "Unable to process response".
Any help you can provide would be much appreciated. I am happy to provide any configuration information that would be helpful if you can provide the CLI commands you would like me to execute.
Seems like it doesn't like DES too much, you can change the cipher to "not" include DES in your policy:
ssl encryption 3des-sha1 aes128-sha1 aes256-sha1
DES in general isn't very secure anyway, and the above cipher choices will provide you with better encryption policy.
Hope that helps.
