Unable to access secondary subnet via VPN

I am having a problem with clients accessing a secondary subnet via VPN.
Clients on VPN are given the address on the 192.168.15.0 subnet. Once connected they can access 192.168.16.0 (Production subnet) fine, but are unable to access the 192.168.8.0 secondary subnet. If you are on the 192.168.16.0 subnet in the office you can access 192.168.8.0 subnet fine. The traffic is coming in via an ASA 5510 then traverses a Juniper firewall and a MPLS router to the secondary subnet. I'm not sure if it's a nat issue or not. Any help would be helpful.
Attached is the config of the ASA. Thank you in advance
