System Admin: VPN: config error

In System Admin / VPN, I have:
Status:config error
VPN IP:Unable to detect

Clicking on Run Setup produces a “Please wait” dialog, but then appears to do nothing. Are there any log files that might show me what’s happening behind the scenes?

My system info:
FreePBX Distro: 6.12.65-26
Asterisk Ver: 11.16.0
Sysadmin Pro: 12.0.22.1

Thanks.

Since you have installed on the FreePBX Distro you can open a commercial modules support ticket and one of our support techs can take a look and point you in the right direction.
