UniVMAX SE8.2 IP change breaks client SYMCLI connection.

I have a UniVMAX vApp running and have used it as a network service for my local SYMCLI install.

We are in the midst of changing IPs in the Durham Lab and after I changed the IP I can no longer connect using my  SE Windows client.

I have tried resetting the Solutions enabler certificate using the vApp management GUI.

I get "A remote send or receive operation failed" when using SYMCLI LIST

I cannot find out if there is something to reset (cert/key/etc) on the client or the vApp to allow connections again.

I can still connect to other SE/UniVMAX vApps (where IPs haven't been changed)
