I had the same exact issue 2 days ago. Here is how I corrected it.

Configuring Address Pools for Nondirectly Connected Networks:?
?
If you need to configure an address pool for IP addresses from a network that is not directly connected, perform the following steps:?
?
1. Create a localloopback interface and configure it with an IP address and subnet mask?
from the address pool.?
?
2. Configure the address pool with the ip local pool command. The range of addresses?
must fall under the subnet mask configured in step 1.?
?
3. Configure the svc address-pool command with name configured in step 2.?
?

Subject: Cisco AnyConnect Problems with ASA...

I receive the following pop-up when I attempt to establish an AnyConnect SSL
session to an ASA.

Cisco AnyConnect VPN Client

An error was received from the secure gateway in response to the VPN
negotiation request. Please contact your network administrator.

The following message was received from the remote VPN device. No assigned
address.

I do have an address pool assigned to the group in the ASA config.

Debug Output from the ASA is below
