VPN clients can not connect. (Clients have hung up?)

I am running a Mac Mini 2012 Server for a VPN service. I tried setting it up with a domain name, and a very simple shared secret, operating on L2TP and PPTP. I am almost 100% sure that everything has been set up correctly. However, when I try to connect to my VPN (by configuration profile and inputting the settings manually), my devices state that the VPN server failed to respond. This occurs on both my local connection and outside my network.

Inspecting the VPN logs on my server, I notice that it keeps saying that the client has hung up. Here is the logs from a couple days ago

I have tried restarting the VPN service multiple times and even reinstalled Server completely.

Can someone please help me fix this as I am leaving town soon but need access to my local network?

I don't mean to revive an old thread, but I, too, was having this exact problem. The solution for me was looking in the VPN Settings and noticing that under "DNS settings", it listed 2 name servers, clicking edit revealed that there was one real entry, and one blank one. Clicking on, then deleting the blank entry updated the setting to say 1 name server. Viola! Worked first try! Hope this helps you too!

Thanks a 1000 times.

It took me some time to find this same error in the configuration.

Works 100% now.

I wanted to bump this post because it solved the problem for me as well; I've been trying to solve the same issues for about a week now!

manually stop and reactivate the VPN service after every server reboot.
