Product: ASA-5508-X / v9.7(1)4
Hello,
After configuring a VPN on the defined product I am receiving the following error message from the AnyConnect client, and I'm stuck as to where to go from here:
AnyConnect was not able to establish a connection to the specified secure gateway.
Please try connecting again. The secure gateway has rejected the connection attempt. A new connection attempt
to the same or another secure gateway is needed, which required re-authentication.
The following message was received from the secure gateway: No assigned address.
Below is my configuration:

Hi
Sorry if i miss something, I'm reading your config through my smartphone.
I see you're trying to assign your vpn users an ip within the same subnet as your lan and using asa as dhcp server. Usually we use dhcp to redirect requests to internal corporate dhcp server or ip local pool when we want asa to deliver ip addresses.
Using dhcp method when asa is the dhcp server, I'm not sure it works and to be totally transparent I've never tested also.

Thanks Francesco,
I was sure I had followed the guide you referenced and it didn't work ... finger problems I guess.
Thanks again.
