DNA Center stops working

DNA Center stops working.
The web interface is not responding to either the cluster ip address or the real ip address.
So I enter via SSH, and enter "sudo maglev-config update"

I notice that under the interface I have configured (enp94s0f0), the DNS Servers and Cluster Link boxes are empty.
So I enter the information needed.

But when I press done, I get this:

Error: Change of IP addresss of the intra-cluster link is not supported.
But I do not try to change any IP address. I'm just trying to add back in the DNS servers and Cluster Link information.

And when running this command:

$ cat /etc/network/interfaces

I can see that all the information is already there:

pre-up /sbin/sysctl -w net.ipv6.conf.enp94s0f0.accept_ra=0

auto lo
iface lo inet loopback


source /etc/network/interfaces.d/*.cfg

So what to do next?
