FirePower 1100 lost smart registration

[EdgarMurray8920]

I have a FirePower 1100 for my home lab and for some reason, it lost DNS connectivity and lost registration. I did not notice and now I can't deploy changes. I connected to the CLI and tried to ping from system. When I try to ping from system I get the following message 

Temporary failure in name resolution

I can ping 8.8.8.8. Here is my show network command results

I already solved the issue but was away form my computer to update the thread. 

I solved the issue using this thread Solved: Re: Not possible to register firepower 1120 - Cisco Community

The Gateway line will use that kind of IP Address when the option for the Management port to use the Data Interface gateway.

Gateway                   : 169.254.1.1
